I have an identical one running 24/7 for 6 months now. Driven with 100 mw to get full 4 watts out into a panel antenna and it barely gets warm. Works very well and is the only solution that works after trying everything else. Highly recommended. Using it to view this video and make this comment....;-)
I've been having a lot of fun watching your videos, experimenting with antennas and actually having good results. Recently I purchased an Alfa card from eBay and now I get 100% signal and -45dbm atenuation, whereas I used to get 80% and -55dbm with a 7 turn helical connected to my laptops wifi card (20% signal with -81dbm without external antenna).
Definitely a great review and confirms aspects of my experience with using the product. My experience using the EDUP v Sunhans amplifiers on a DJI Phantom 3 Standard is that the lower power Sunhans amplifiers provide a stronger cleaner signal and thus a much longer reach. Using panel antennas and Sunhans 2.5w 2.4ghz and 2w 5.8ghz, I have both signals out to a distance of 7km (absolute limit of battery endurance) whereas with the EDUP 4w and 5w respectively, I start to lose control signal (5.8ghz) at 4km. I would be interested in seeing a comparative test of the Sunhans amplifiers
3:40 - That isn't a warranty sticker. That's just a quality check sticker they use to mark their products when they have been checked for quality, also for added reassurance to the consumer.
Using this amp with a much larger 9dBi segmented Omni antenna results in a cool amp. I've tried it as an AP and Station on a USB adaptor and direct to a TP-Link range extender. That is with various videos being run to load up the network. It works very well and drags in signals from across the next few streets. More than a 9dBi antenna on it's own. The bigger antenna is the best and cheapest upgrade. This just takes it a few steps further. I saw the vid on RF cables and the ones that come with the longer antennas have a mag mount and 1M or more cable. Ditch the cable and screw the antenna to the router, extender or antenna direct. Makes a big difference as measured on this channel.
You are absolutely right. There are cables capable of high frequencies, but those are far more expensive than screwing the WIFI-receiver/transmitter directly to your antenna and powering it over ethernet (PoE). Some high-frequency cables can cost hundreds of dollars/pounds per yard/meter. Cheap coax-cables give a huge loss. Increasing the power doesn't have the huge effect as the numbers would suggest. To double the effect at the same distance you'll need to increase the power by 8 times. It's far more efficient to use directional antennas and that disturbs the signals of your neighbours far less.
Will be trying this as a Wifi booster for camping. You can not boost what is not there but often the signal is weak. Using an external directional antenna and router, it will be interesting to see if it works.
I made a dipole for 2.4ghz with a total length of 6.25 cm, that split in half for each side of antenna at 3 cm worked out well fo me. I was only testing directional properties with this antenna. I like your channel. Post some more topics.
I've warenteed a couple of things back to Chinese ebay/alibaba vendors, never had a problem. I'd say they were actually a lot more helpful and a lot more interested in keeping me happy than most vendors from my own countries.
Andrew, a friend of mineI purchased a 2000mW 5.8mHz transmitter from China for FPV. He realizes that it can't be used in the US but wondered what kind of range could he expect to get from the simple dipole antenna that comes with it. I don't know the Brand but the top reads TX52W, It has a built in fan, a small blue LED inside that lights up when power is on, it also has a number of inputs and output pins marked S-CH | VIDI over S-V | VID2 each section has 3 pins over the top of the markings. A second set of markings and pins to the right of the first have the normal pins for an FPV transmitter sound and yellow red and black wires with voltage ranges from 7-24 volts. Speaking of sound, you sound like you're in a mine shaft, very muted, lots of bass, you would sound much better with mid-tone and high tone treble...
absolutely incredible. Thank you so much for taking the time to do the video and set up the jig. I bought 2 of those exact amplifiers and one 5.8 which was actually very hard to get but they all match and connected it to my drone which happens to be a DJI Phantom 3 4K. I was awfully confused as the only thing that I have to go by are the specifications as testing equipment at that frequency is way too expensive and I haven't been in the amateur radio game and a very long time. anyway my results were about the same as yours in the physical. I improved my Wi-Fi Telemetry and Video Connection as well as control about 20% to 25%. now comes the confusing issue , if I brought one tenth of one Watt to 4 Watts, how come the increase was only 20%? I know there are a lot of factors and I won't bother listing them but somehow I am wondering if I'm over driving the front end of this little amplifier. any thoughts? just getting a matching Network would probably be expensive if I couldn't build it and I don't want to put an attenuator on it as my fear is that it would then limit the receive which is absolutely essential in bipolar Direction. so frustrating but I only spent $24.54 on each amplifier compared to double triple or quadruple that of others with the same or less specifications. if you have any thoughts or suggestions to improve my results I would gladly make a donation. LOL
Would this also work on Bluetooth since BT it uses 2.4-2.483 GHz? Could you use a splitter to connect one amplifier to two directional antennas pointed in different directions?
Thank you for another great video. At 9:00 you highlight a spike which appeared to be in the 1800 MHz gsm mobile phone band and a very wide spread of frequency around 2.4ghz. Please can you give some additional information about what input signal was presented to the amplifier?
Hawk Moe I've already installed 24 of these amps at my clients homes. These are cheap $25 amps that work quite good. But if you buy Sunhans 4W amps. They work a whole lot better, but costs about $100,- for 4W 2.4GHz and $130,- for 5.8GHz. I use them for Wifi and RC Quadcopters and planes. I also installed them at 10 of my clients. They don't run hot like these ones. Have a lot less noise. And give a far better range.
@@ernestoditerribile I'm looking to get a dual 4w 2.4ghz and 5.8ghz in one but can only find a 2w. Do you think a 2w will make a good difference? I plan to use them on mavic pro and phantom 3 professional. Would love some advice from anyo e with experience. Thanks
Yor Highness you get N connectors on 10, 20, 30W and outdoor versions. But that kind of power is most of the times unnecessary. You only need that kind of power if you live on a farm, or have a very big warehouse, terminal or factory. But for that kind of companies I'll advise to buy a mesh network from brands like Strix or Ruckus. Those systems work really great. With strix you could still connect 4 directional Yagi Antenna's per mesh router. You could still connect 10W amps on them if you don't want to buy to many Strix routers.
I'd love to see more amplifier tests - I'd use one for the 13cm ham band. Would it be easy to add an external PTT for SSB? Don't they get to hot when operated on FM/CW? Btw: At 9:00 That out of FCC spec signal at 1.x GHz (on a UMTS band I guess) - You weren't still sweeping with the TG, were you? Garbage in/garbage out? :)
I have one of these Amplifier, the red led get on and also the green one is blinking, but the amplifier doesn't take more than 60mA and never get warm. what is the problem with my amplifier?
Don't buy this thing if you want faster internet or longer range with flying thing. Buy this if you need amplification with massive amounts of noise. Yes you can see much more access points when scanning but try test speed. Speed test shows extremely poor speed even with close APs because of noise. And for fpv forget it. Tested in both environments.
Great Job, do you think these type of booster will work well with your Cisco 2.4Ghz Antenna. They are many boosters on the market, like Sunhans or Comfast 4W types. Which is the best
The unit of measurement for power is Watt, denoted by a large W. The Chinese note the units of measure with w or W as they do not distinguish uppercase letters from lowercase letters - they have a different alphabet. I watch your videos and I appreciate them. Are you Chinese? James Watt was Scottish, en.wikipedia.org/wiki/James_Watt and www.britannica.com/science/watt-unit-of-measurement.
Hi Andrew! great video :) I´m living off gridd in a remote area and used to enjoy internet through a simcard in a4g LTE 300mbps wirelss router. It does not have external antenas. As of few weeks back my connection has been terrible and offline most of the time. How can I do some home made improvements or make an antenna of some sorts to amplify? Perhaps youve made a video on such a thing in the passed but I wasnt sure which one it was from the list. Thanks for your efforts and be well :)
It`s the best test of amplifier!!! I always wanted to see characteristic of 2.4GHz amplifier and all it noises with spectrum analyzer. It is very helpful. Could you test the speed of connection with this amplifier? Can it correctly work with high speed standards like 802.11n or it reduce speed ?
i was just wondering if they not only boost the signal outgoing.. but do they boost the incoming signals too?? and if you don't plug in the power to the amplifiers can the WIFI device that's getting boosted still receive signals still even with the amplifier off?
I can't see how wide that noise spike is under your cursor, but it's close enough to 1.8GHz which is/was a common Intel clock speed - any chance at all that this is coupled in from your PC?
Sir Andrew, i hope you don't mind me asking question about how much a typical mobile phone's 3g, 4g receiver's wattage or power is using. i been trying to build and calculate the size of an antenna base on its wattage to maximize its receiving capability. it doesn't have any marking of how much wattage it is using. and when i googled it, i got confusing variety of answers and i wasn't sure which. since you aare a pro in this area of studies, i take the opportunity of asking you this. I've been following and watching your videos, and i have learned so many things. thank you so much for making such informative videos for people like me with very limited tools to use.
Andrew has far more knowledge and experience than I, but here's my 2-cents: In communication both ends are transmitters as well as receivers. There are always packages of data going to and from. Therefor each transmitter is also a receiver and the other way around. If you are downloading, you are also uploading acknowledgements of the data received. Often though the speeds don't have to be equal. Often the download speed can be higher because receiving the full data costs more data transfer than the acknowledgement. That's called asynchronous: your connection is optimized for your use of downloading. If however the acknowledgment of receiving the data doesn't reach the sender, the sender will send the package of data again (and again and again) which makes the transmission very slow. The wattage on the receiving end only influences the power for sending data or acknowledgements. It cannot increase the power of the packages of data received. The signals received are picked up by the antenna and disturbed by all the other signals in the same frequency-range. If you use an amplifier on the receiving end, you not only amplify the data you want to receive, but also the disturbance of the signals you want to exclude. Therefor using an amplifier on the receiving end is quite useless. You'd better use a directional antenna that only takes the signals you need.
So if you amplify the transmit but not the receive, then what is good about that? If I have this connected on my router, that doesn't necessarily mean I can have a longer range coverage if the receiving end isn't also amplified, right? I mean my remote device, like my wifi connected cellphone/tablet, would be able to see my router BUT it would not be able to connect because the transmit signal on my phone/tablet wouldn't be strong enough for this amplified to pickup, right?
Andrew McNeil ...great review and test! I have two on the way from China...my question is...this product has a maximum trigger input of 20dbm which is low to my understanding about 0.1w ...does this mean I cannot send a stronger signal to it? I'm in a CE region which is 23dbm 0.2w ...but fly quads and have my birds talking in 1.5w and have to have my RC throwing out the same if in that mode....can you please give some insight...cheers
Hey Josh did you get any more insight into this as I'm about to boost my mavic platinum and phantom 3 professional and maybe P4P too and I'm interested in the answers to your questions. Thanks
I bought one of this after this review. Added an old AMD heatsink on its bottom to play safe and it really did improve my connection a lot. Fuck my neighbors, I'm pretty sure two of them have a couple of these things too.
Would it work at all at half the voltage? Even if it does, the power would probably be less than half at half the voltage since currents would also be less. Maybe three-quarters voltage would be a better bet? If some transistors aren't opening fully because the voltage is too low, they might drop too much voltage, overheat and break, IDK.
question.. I do not own any 2.4ghz analyzer or a wireles router with a removavle antenna.. so I'm not quite sure if this device is transmitting or not.. now I've notice that there are two led lights on the booster.. What does the red and green light mean (red= transmit abd green = receive ?!?) I'm going to use this to get more range on my FPV plane..
Hi friend..! What does this amplifier do?? It is used to broadcast wifi signals from router to far distance ?? OR It is used to catch weak long distant wifi signals and fed to laptop wifi adapter SMA port ??
I've just bought this edup 4w amp as an upgrade and pleased to see your test shows it outputs the claimed power, have you ever tested the turbowing RY-2.4? I've had one on my rc transmitter for a few years and its not clear what they output. Sellers state it as a 1w amp but the manual says its 1w in one part and 2w in another part but opening the unit and looking up the output transistor brings up a part that can output 2.5w. I've always been sure its kicking out more than 1w. Another module I'm interested in knowing about is the Wii-link XQ-02A which claims 2w from a 100mw input, and thinking of using them as part of my open HD FPV system as they are very lightweight and can be carried on board a plane :)
Hi, I got this amplifier a few days ago and I have tried to connected with my MJX Bugs 2SE and it seems that with a battery bank or a battery doesn't work properly, if I use the given power supply or a 12volt supply through a phone charger it seems to work fine !!! What am I doing wrong?
@@stevefox3763 Thanks for the quick reply, I am using 5V power bank + step up adjustable supply at 12V and 2Amp current or 4.8V and 6V batteries at 2200mAmp + step up adjustable supply. I am using the same configuration to power up a repeater router at 9V and it seems to work
@@JRMOBILE I think your boost module is the problem, they can affect rf gear really badly as the way they invert the voltage causes a tonne of interference. Have you tried to power the amp straight from a 2 or 3s lipo?
Definitely a must, I run mine with 12v. 2.4ghz 25mw cheap hobby king hsks 6s radio. I added a 300gm heatsink and a fan. It really starts melting stuff after 38minutes.
hi Andrew. I have one of these and have just popped it. put the - and + the wrong way around. could you read the chip I'd on the 6 legged black chip nearest the power input jack for me? this has popped and is unreadable for replacement :-( thank you bud :-)
Very nice video 🙏😊 would be great to see more videos about 2,4GHz Amplifier maybe with this much china pcb s without case from 10-30dollers Regards from Germany
hello i have same booster how can i underestand is it working or not becaouse when i connecting power i cant see led indicators light is it broken ? :(
Great video :) subscribed! i have ordered a dual band antenna for my dual band phantom 4 pro controller, i would like to boost the signal .. is there good dual band boosters like this that will auto switch between 2.4 - 5.8 ?
May I know if it uses its own spectrum and disturbs the frequencies within the vicinity? What is the different between the wifi signal amplifier and cellular signal booster? I really need your answer before I buy because in Malaysia cellular signal booster is illegal and could be fine up to RM 500k.
If you can use directional, directional antennas would give you far more boosting than increasing the power. Especially if you want to set up a point-to-point connection.
I will buy this amplifier and i will use it with alfa awus036nha for fake access point. Can this amplifiar work properly for me? My alfa is already 2 watt. Is this problem?
I had that WiFi adapter and it died in less than a week, I did not use an amplifier with it. In the process of returning it to seller currently. Interestingly it was bought from eBay but delivered by Amazon. It seemed genuine with the correct chipset and hologram etc.
Hi: Can you explain to us about the antenna being a dipole & not a vertical? If your antenna is a dipole then polarization becomes CRITICAL but I’m pretty sure your antenna is a vertical which would be omnidirectional. Thank you VE6??????
these are illegal and no longer sold on any of the websites. they amp the signal way beyond the FCC limits, even tho the stickers on the box "claim" its legal.

Therefor using an amplifier on the receiving end is quite useless. You'd better use a directional antenna that only takes the signals you need.
The green light is flashing.
Is dat good.
Thanks
So if you amplify the transmit but not the receive, then what is good about that? If I have this connected on my router, that doesn't necessarily mean I can have a longer range coverage if the receiving end isn't also amplified, right? I mean my remote device, like my wifi connected cellphone/tablet, would be able to see my router BUT it would not be able to connect because the transmit signal on my phone/tablet wouldn't be strong enough for this amplified to pickup, right?
Andrew McNeil ...great review and test! I have two on the way from China...my question is...this product has a maximum trigger input of 20dbm which is low to my understanding about 0.1w ...does this mean I cannot send a stronger signal to it? I'm in a CE region which is 23dbm 0.2w ...but fly quads and have my birds talking in 1.5w and have to have my RC throwing out the same if in that mode....can you please give some insight...cheers
Hey Josh did you get any more insight into this as I'm about to boost my mavic platinum and phantom 3 professional and maybe P4P too and I'm interested in the answers to your questions.
Thanks
I bought one of this after this review. Added an old AMD heatsink on its bottom to play safe and it really did improve my connection a lot. Fuck my neighbors, I'm pretty sure two of them have a couple of these things too.
Im also interested in more booster videos
how about giving it half the voltage for half the power but a longer life?
Would it work at all at half the voltage? Even if it does, the power would probably be less than half at half the voltage since currents would also be less. Maybe three-quarters voltage would be a better bet? If some transistors aren't opening fully because the voltage is too low, they might drop too much voltage, overheat and break, IDK.
question.. I do not own any 2.4ghz analyzer or a wireles router with a removavle antenna.. so I'm not quite sure if this device is transmitting or not.. now I've notice that there are two led lights on the booster.. What does the red and green light mean (red= transmit abd green = receive ?!?) I'm going to use this to get more range on my FPV plane..
Red is power is coming to the unit, and green the transmit signal
Can it be used with ALFA wifi AWUS036NHA to amplify range ??
Um. They ALL come from China bro😶
Andrew, you said this gets hot and that it may go pop if the swr is wrong. So must I not use it with an Alfa and home made sat dish with cantenna?
Great test!
Would this work for a backup camera to amplify it
What if you ran two of these together in tandem would you get 8wt
This was on 24/7 I'd mount a fan on it
what is that extra part passed the ground plane?
Hi friend..!
What does this amplifier do??
It is used to broadcast wifi signals from router to far distance ??
OR
It is used to catch weak long distant wifi signals and fed to laptop wifi adapter SMA port ??
hi when will you have your long range repeater back in stock!
what inside the box, can you show me
I've just bought this edup 4w amp as an upgrade and pleased to see your test shows it outputs the claimed power, have you ever tested the turbowing RY-2.4?
I've had one on my rc transmitter for a few years and its not clear what they output.
Sellers state it as a 1w amp but the manual says its 1w in one part and 2w in another part but opening the unit and looking up the output transistor brings up a part that can output 2.5w.
I've always been sure its kicking out more than 1w.
Another module I'm interested in knowing about is the Wii-link XQ-02A which claims 2w from a 100mw input, and thinking of using them as part of my open HD FPV system as they are very lightweight and can be carried on board a plane :)
Hi, I got this amplifier a few days ago and I have tried to connected with my MJX Bugs 2SE and it seems that with a battery bank or a battery doesn't work properly, if I use the given power supply or a 12volt supply through a phone charger it seems to work fine !!!
What am I doing wrong?
@@JRMOBILE what's the voltage of your battery supply and are you using sufficient wiring?
@@stevefox3763
Thanks for the quick reply, I am using 5V power bank + step up adjustable supply at 12V and 2Amp current or 4.8V and 6V batteries at 2200mAmp + step up adjustable supply.
I am using the same configuration to power up a repeater router at 9V and it seems to work
@@JRMOBILE I think your boost module is the problem, they can affect rf gear really badly as the way they invert the voltage causes a tonne of interference. Have you tried to power the amp straight from a 2 or 3s lipo?
@@stevefox3763
No, not yet anyway, that would be my last resort, I will buy a 3s lipo and take it from there thank you, much appreciated 😄👍
What about mounting it to a larger heat sink? fan cooling?
Definitely a must, I run mine with 12v. 2.4ghz 25mw cheap hobby king hsks 6s radio. I added a 300gm heatsink and a fan. It really starts melting stuff after 38minutes.
hi Andrew. I have one of these and have just popped it. put the - and + the wrong way around. could you read the chip I'd on the 6 legged black chip nearest the power input jack for me? this has popped and is unreadable for replacement :-( thank you bud :-)
Very nice video 🙏😊 would be great to see more videos about 2,4GHz Amplifier maybe with this much china pcb s without case from 10-30dollers
Regards from Germany
great video keep them coming
hello i have same booster how can i underestand is it working or not becaouse when i connecting power i cant see led indicators light is it broken ? :(
Hello Sir, which one of them is better? Sunhans 2500mw or 4w booster from china?
Been using the 4w and no regrets. Is inmensely powerful and got wifi signal past 2.5km using stock antena in an atic
its ok direct into yagi antenna
so this is of no benefit connected between an Alfa and antenna?
Can you use this booster on a usb wifi card ?
band 3 is 1.8Mhz, can you use this to amplify the LTE signal in your opinion?
que la berga no entiendes de que trata el video o que? hacen demaciadas preguntas fuera del tema
what about using it with the x9d taranis radio? would it work well?
Great video :) subscribed!
i have ordered a dual band antenna for my dual band phantom 4 pro controller, i would like to boost the signal ..
is there good dual band boosters like this that will auto switch between 2.4 - 5.8 ?
Please tell me how you went with your phantom and the boosters. I'm about to do my mavic pro and phantom 3 professional.
do these amplify the recieving signal aswell?
getting the 2.4 ghz wifi booster for the drone i have
May I know if it uses its own spectrum and disturbs the frequencies within the vicinity? What is the different between the wifi signal amplifier and cellular signal booster? I really need your answer before I buy because in Malaysia cellular signal booster is illegal and could be fine up to RM 500k.
This is only for 2.4GHz cellular uses completely different frequencies. It will not work
@@andrewmcneil Thank you very much for your answer sir. Now, I may consider on buying it without any hesitation.
On the evening he puts his tx next to a can of soup and voila hot soup
How can i get 2.6 Ghz booster?
very helpful, thank you
Is there a 2 antenna version
As far as I know, there isn't. However, using two of those should work if you position the antennas correctly apart.
What kind of connectors is it using on the input and output side of the booster??
Rp-SMA connectors
can i use external antenna with this ...
where do I get a 2.4ghz booster for transmit and receive which is reliable? It need not be as high powered as this. Thanks
If you can use directional, directional antennas would give you far more boosting than increasing the power.
Especially if you want to set up a point-to-point connection.
I will buy this amplifier and i will use it with alfa awus036nha for fake access point. Can this amplifiar work properly for me? My alfa is already 2 watt. Is this problem?
I had that WiFi adapter and it died in less than a week, I did not use an amplifier with it. In the process of returning it to seller currently. Interestingly it was bought from eBay but delivered by Amazon. It seemed genuine with the correct chipset and hologram etc.
In strapping that to the back of my quad-copter transmitter - how is it then powered?
try 9 V battery
I have built 18650 cells in remote + xl6009 boost. That powers this amp but its no use. Just bad amp. Better antennas are way to go.
@@pahvilaatikko9587 sunhans any good? If so which one? I'm sure I need dual band 2.4ghz and 5.8ghz
does this work with dual band?
how i can buy its? shoppind link plz
how come your "wifi meter" went from 3/% to 2/5 when you put on the amplifier? is the signal noizy?
What voltage used to power the unit? 12 v ?
Can I power it with 9 V ?
It comes with a 12 volt adaptor but is listed to run from 6 to 16 volts.
It will interfere with tacan and dme aka navigational equipment for aircraft.
Can an alfa support an 8w amplifier??
The eBay link no longer works
Owey just because you're using that bogus amplifier LOL
Nice video
Can this be used in radio transmitter?
That's what's made up for, it will get unimaginable hot. Using with a hobby king hsks 6s
Give me a $0.05 capacitor and I'll give you another bogus product that turns your house wiring into an antenna LOL.
Hi: Can you explain to us about the antenna being a dipole & not a vertical? If your antenna is a dipole then polarization becomes CRITICAL but I’m pretty sure your antenna is a vertical which would be omnidirectional. Thank you VE6??????
is this legal to use with a foundation licence in the uk?
where do I get one, please?
see show more
these are illegal and no longer sold on any of the websites. they amp the signal way beyond the FCC limits, even tho the stickers on the box "claim" its legal.
LOL
@@andrewmcneil yep I've already contacted the fcc about it and they are no longer allowed to be sold in the US,. you wont find them on any american facing e-commerce sites.
