This antenna actually works great, but it needs some workaround/mod before u can get best of it. I've got some fantastic results with this modded antenna. This antenna should be placed outdoor, and u need to cover back of antenna (fully) with aluminum tape to reject reflections. Then u should make a small cube from metal grill/net approx 35cm x 35cm and put the antenna inside of it. The cube is open only to one side, antenna facing forward. Its all about getting RSRQ and SNR to decent levels. I bet every antenna works better outdoor than indoor, but its about rf interference and how to handle it. This antenna has RG-174 cables, which are shitty as hell. I taped these cables with aluminum tape and added ferrit rings on both end. I recommend chancing these cables to LMR200 type or other low loss cables, since the longer RG-174 cable will add 7-10db to RSRP which is catastrophe. I do also have 2x yagi mimo antennas pointed towards the cellular tower (300 meters), but they have much lower SNR and higher RSRQ, so this 4g antenna works better if your cel tower is near you.
Someone who actually understands RF (unlike the person who posted this video). Time we had a channel from people like this who used to write for Practical Wireless, Wireless World etc. i.e. people who actually know their theory. Can anyone point me in the right direction, please?
Same experience. Internal modem antenna was about the same db, not the -35db promised. Thanks for cracking yours open. Might as well be a pie tin in there.
as you have seen there is nothing in there, no elements,no reflectors, no electronics so must have the same gain as a standard antenna. Twin yagi cost me £20 for the 2 and a bit off playing to make bracket but havnt looked back, std antana 1 bar yaga 4 bar flashing full house of 5 bars.
Have tried a few external antennas too. Most of them just on par with the built in. One stands out however - the LF-ANT4G01. I got a very nice increase of the important RSRP from -93 dBm to -81 dBm at works (-78 when best). A massive 12 dBm increase. I had the issue that the local tower goes into power save during the night and so only B20 band (800 MHz) has great strength but strength of B1 or B3 (2100 and 1800 Mhz bands) when upped in the morning wasn't quite enough that router switched back to them even though they're much faster. The 20 Mbps up/down during the night is fine but it's a tad on the low side during the day and so I could just as well had kept my ADSL. I could then restrict my router to use the 1800 MHz band (no 2100 restriction for some odd reason although it can use that band) but that'll result in extremely bad upload during the night at ~1,5 Mbps - not ideal when you have surveillance cameras that needs to be able to upload relatively fast. With this switching to B20 at night and back to B1 or B3 in the morning seems to work flawlessly - no more morning routine of rebooting the router - Yay! While it was not my main motivation to try the antenna it even upped my download to around 180 Mbps when best (100 worst) while before it was 50-80 and upload seems maxed out at 50 - nice! As others say the position of the antenna is important - also with the LF-ANT4G01. Actually it's best when it's not pointing directly towards the tower - so play a little with it. The current spot I've placed antenna in I've also the router in so it's not just position. The LF-ANT4G01 actually is better than the build in antennas by a good margin - although of course not the exaggerated 88 dBi claim. The construction of the LF-ANT4G01 is also very different from the one you got there (you can see pictures of it by searching). The one you got I believe is just two dipoles. Probably great for high outdoor placement but indoor performance is nothing to talk about - you might as well just stick a thin piece of wire (of right length) in the external antenna connectors then.
I use one of these for a ADS-B antenna with a 1090 filter built in. Gets better reception than most off the shelf small adsb antennas. But only on one of the antennas. One sucks the other is great. (one of the antennas in this thing)
Except for the crappy plastic container there's not much different quality from the near $90 unit I just bought. Tear down any of these 4 G antennas and be prepared for a shock. Not a lot inside for your money.
I have experienced some gain with this antenna, although not the 35db they claim. Its actually a copy of an antenna made by Panorama. I'm not sure why anyone would expect to see reflectors or electronics inside a non-active wideband panel antenna. If you want better performance buy some copper tape and an IP Enclosure and make your own, its very easy and there are even plans online to help you.
i never had any luck with this antenna, i run twin yagi now, yes i have seen some good builds about even started to build one once has a double diamond driver from memory.
You don't need to pull it apart to figure out why it doesn't work. The physical size of the antenna, being omnidirectional is that of a 3dbi or 1dbd design. Confirmed by what you found, it is just two dipoles . Then subtract the loss in the crap coax and even at 700MHz (B28) you'll get less signal than the internal modem antennas, which is actually also an issue for well-made desktop antennas. These clowns advertise them as 35dBi, which is not even close to being practical nor physically possible . The marketing team just removed the decimal point from 3.5dBi to make it 35dBi ! Now, despite the crap design it is possible to get better performance with an indoor antenna by placing it in a location where the signal is good such as a window. Placing the modem in the same location will achieve better results.
Fully agree, did look for a comment i made to someone about 2 weeks ago where they sent me a link to another one quoting 45dBi, my reply was single digit dbi if that
Wrong ! "All antennas with two cable connections are MIMO antennas. With 4G MIMO, one antenna is polarised at a 90-degree angle to the other. This effectively doubles the bandwidth by transmitting on opposite polarities simultaneously within the same band"
These work just fine if you mount them against a window (or outside) There's no point sitting it on the table next to the router and then saying oh well it doesn't work lol. Any antenna will be shit if you do that. One of these gave me about a 30mbps increase in speed (from 80 to 110). Thanks for the tear down nevertheless.
@@WitoldWnuk not the signal, the speed. 80mbps to 110mbps. It does however increase the noise as well so if you had a medium to low SNR before it maybe worse
Thanks! Sure wish you could have measured everything. Like from solider joint to bottom of 91MM antenna pad, Also the ground plane measurements would have been very helpful. Nevertheless, I do appreciate the video and thumbs up.
i now use twin yagi mounted outside, found out what cell tower was being used and pointed them in that direction, works great, purchased from gearbest 4g yagi about £10 each
Would a Yagi antenna work indoors next to a window? I currently have this consumer.huawei.com/en/smart-home/lte-router/tech-specs/b315-en.htm and only getting 1-2 bars on the 4G connection. Would like to at least get 3 bars. I can't do external mounting.
It may work but not recomended. first thing to do is to look on your routers setup page to see if it tells you what mast its connected too then locate it on google maps compared with your location, if you have no obsticals between your window and the mast it may work, if not then a omni directional antenna may be better.
hi i fallowed your advise to check out a twin yagi but i found nothing on that site with the title twin, im looking for a antenna for a huawei e5786 , any advise appreciated, Cheers!
I made the twin out of 2 x single yagi's and made a bracket to support them, they were this part www.gearbest.com/networking-communication/pp_259886.html?wid=21 of you prefer banggood then i would imagine this is the same part www.banggood.com/Yagi-2_4GHz-25dbi-WiFi-RP-SMA-Antenna-For-Wireless-Router-Outdoor-p-84566.html?rmmds=search i am planning on doing a video at some point.

Kevs Electrical Workshop Well its very nice of you to share details, this is a nightmare for me, have you tried other antennas like for example a magnetic type or omni types (bit expensive from what i seen)?
depends on your requirment, if your instalation is static then a beam (yagi) is the way to go, if your instalation is mobile then omni is the better choice if you have a fair signal. there is also lots of designs on the internet to build your own for basicly nothing
Kevs Electrical Workshop so all those antennas online that say they are only compatible with certain Haewie can all work, its just some adopter? the coverage in my area is very poor, very low, i have to leave the place and walk about 25 feet just to make a phone call, will an antenna help this?
with a adaptor you could use other non huawei antennas, the antenna will only help the device its connected too. you could ask your service provider for a booster, Three offered me one years ago as my signal was bad at home
+Laurence Lee sorry to say i didnt notice any improvement over my routers standard antennas, it does give you the ability to mount in diffrent location.

maybe he means a 4g router wifi
ill trade mine had unstriped wires hot glued to th airals with a resistor in the hot glue.
realy they didnt even have exposed wire in the hot glue!
Wow at least they made a bit of a effort to make something that wont work on mine.
It’s simple to make one
Sh*t ... I wish i have seen this before buying one, what a waste.
