Hi, I have a cottage in the woods of Sweden where 4G coverage is not the best. I have a Huawei 4G router which have given me between 6 and 10 Mbit/s download and 3-5 Mbit/ upload, which I can live with. I watched your video, and thought I would have a go at making this antenna. It didn't turn out as nice as yours, but I changed out one of the original antennas with this one and I got 19-23 Mbit/s download and 13-15 Mbit/s upload speed. I am very pleased with the result.
Thank you so much Andrew.
Some folks just make this look so easy.
I like the soldering technique!
I'd like to see you make more 4G & 5G antennas. I live in an area that cellular signal is pretty weak in (-100 to -120 db). I'd also like to see how you connect two of these to an amplifier.
Just found your channel love it! Most MNO in UK use band 3 and band 20 lte I think, well LTE800 and LTE2100. So an antenna with best response at those bands, rather than wide band including 2.3gig, 2.7 and up to 3.6gig for 5g would be real useful. In addition, since in rural areas L800 is used most (coverage rather than capacity) having a high gain log periodic or something that is sturdy and tuned narrow-band for say 700-900 would be of use for a lot of people
Thumb up, as usual; thank you for all these interesting tutos
No problem glad you enjoy them
Awesome, just built canntenna from u very happy, I'll built this
Greetings Andrew, always a very inspiring video each time. I have just got into plane tracking using ASD-B and was wondering if you had any ideas for improved reception of signals at 1090MHz
Thank you very much. It works well and the satisfaction is priceless.
im looking forward to building this, thank you andrew for the plan.
one thing i'm not sure of is the 26mm section at the bottom obviously the 15mm leg is at the centre at 13mm but what is the spacing for the 20mm legs from the centre? thanks, carl
Great little antenna, I'm aways amazed that you can combine different antenna elements to achieve multi band antennas.
I have a lot of antenna elements from cellular sector antennas.
I can send you some if you are interested, they might be interesting to take a look at :)
Greetings,
Michael
I would be interested yes email me and I will cover your postage costs. It is always nice to take a look at the more professional antennas and compare them to what you can buy on ebay.
You've got mail. :)
Great! You are moving forward towards LTE not just Wi-Fi 👍. Any tips on adding a horn to an LNB? I have the Bullseye for the QO-100 amateur 🛰 that I would like to receive from inside the house behind the window of course. Thanks
Really do love your content Andrew, hoping you can answer a question for me.
I am on the edge of a fairly good 4g/lte signal, main problem is quality of signal even using a Poynting omnidirectional antenna, I have however found a far better signal some 40 metres from the house down the garden, problem is getting that signal back to the house, how would you suggest this be done without degrading the signal?
Very interesting with these squares that reduce the antenna size. Thanks for an inspiring video!
Yes it is the same as loading coils on dipoles
And at higher frequencies you don't need a loading coil at all - it's all magic based on the LOCATION/POSITION of the dipole in the waveguide! (time to get out the Smith Chart...)
Nice work bro keep it coming 😊😊😊😊thank you very much for your time & kindness, thanks
Hi Andrew. Interesting video and antena solution. Does it can be used as passive repeater with same antenas on each side coaxial wire? Thanks for your advice.
are the angles of the 15 mm and 20 mm parts important, also where the 20 mm parts attach to the 26 mm part?
What about the distance between the two 10x10 mm squares.. the angle of the 15 mm part could fix those, but maybe that is easier to define?
Thanks
can these antenna be stacked up to increase gain? eg use 4 or 8 of them on a single wire lead? and what would be the best way to do that, stacked vertically on the same orientation? or stacked at 90 deg to the lower one. (I know we need 2 of them/2 leads MIMO) on some routers, when you attach an external antenna, it disables the internal one. so how much gain would one need for it to be effective?
hi love ur videos.. ill like to ask.. i bought mobile signal booster.. i want to split it signal bcoz come only one ceiling antenna ..so try to make the antenna 4g one more to split the signal to make more signal coverage.. can i do that with this?
Very interesting. I shall have a go at making a pair of these.
Yes it is a nice one to start off with
@@andrewmcneil I was going to splash out on a Poynting antenna, but I think I'll experiment with your design first. I live on a narrowboat, and the cellular net works are really the only affordable option. Most of the time download speeds aren't too bad, but some places are a bit marginal, though sometimes a 100 meters in either direction can make quite a difference.
do you have a design for 700mhz starting?
Is this going to boost 4g network coverage in a poor signal area?
if u want to add a reflector what distance it need to be?
i made one and it gave me 5 to 8 mb improvement download!!
i made it whith thin copper wire and the mesuraments are not perfect but it work!what?
i sitck it to the window and then i put aluminium foil as a reflector whith a paper between and it helped!
sorry nmy english not perfect
thank you
Hi. I'm still a little bit stupid with antennas but I bought all the stuff to make one similar to this....
Can this design and proportion be scaled up in size equally and it still function.?
Or is the size critical to its working freq??
Any tutorial what it takes to design antenna?
Hello Andrew, as per other comments, is there a calculator for this antenna? (4GX (Telstra AU) is 723MHz/778MHz) (Would build a Yagi but they are difficult to make mobile).
Hi Andrew, just wondering if you've done a video on creating an omnidirectional antenna dedicated to bands 20 and 8, that is with a good response from 800Mhz upto about 1Ghz. This would be very usefull for me in my rural, non - line of site position. If so, could you poitnt me to it please. Thanks, Keith
How to adjust this anntena for high gain? On single 2100mhz frequency
Always find this fascinating. Practically, some sort of booster for mobile signal would be great. Any thoughts Andrew?
Thanks. Useful for my Parrot Disco 4G LTE Softmod fpv project, huawei modem
Let us know how you get on
andrew mcneil sure will do. Thanks
Hi is there any way to catch 4G signals from every direction with one antenna?
Once again please, what for wire (metal) did you you use for building the antenna? Where is possible to buy it? Thx!
1.5 mm in diameter. 15 gauge (1.45 mm) copper wire would work I think
Hi, would you consider making and selling a version that would work on Three network - 800, 1400 and 1800mhz. Thank you
Hey andrew i i have been researching the 5.8 antenna in my dji mavic mini as
it has a crap range in aus due to the transmitter being redused in
power. The mini uses two pcb antennas about 5x30mm and i noticed they
do have little squares in them kinda hmm I would like to make a couple of rhp
clover leafs from your video and hang them out side the craft. Do you
think i this will help at all with just a standard control or have to put clovers on the remots hmm any
advice? cheers.
I had experimented clover leaf on 2.4g controller back in 2012 and the experience was very interesting. At first, range seemed to be improved as the RX did not fail-safe in spots of the kitchen where it used to. In my excitement, I went out for a range test, walking with the RX in hand, and the TX hanging at the window. But the range was 40% less than with using its original rubber ducky antenna. A few weeks later, I learnt that circular polarized ants are needed on both sides coz a mismatch in polarization will halve the signal strength (-3db). Then I put cloverleafs on both sides and took my RC heli for a blast. When I moved the throttle stick the tiniest bit, the heli would jump erratically. Then I realized that the radio controller did not like any antenna with signal element that’s shorted with GND (eg: the cloverleaf). I switched to a homemade directional 2.4g crosshair several weeks later, and it solved the problem (as the signal elements on crosshair do not short with GND). I got a fantastic RC range with wide RF beam and also the circular polarization eliminated multipathing, which removed unwanted reflections (interference) like the first discovery I had in the kitchen.
@@terence79chan Yeah that's what i kinda figured so i went with two much larger broadband pcb antenna instead,thanks for your reply.
Andrew can you make high gain antenna fro 2100mhz frequency. Please
Hi,
Would this work for Three UK's dual-band setup of 800 and 1800 Mhz respectively?
If not, which bits would I have to extend/shorten?
Interesting ua-cam.com/video/dx6AqhGdmlM/v-deo.html
The shape seems identical so similar results I guess.
could you do 4g for a car (omni) with more gain, please
Now we have the antenna. What device is used between this and mobile phone? Router?
Greetz Andrew, first off thanks so much for your many videos on the subject, great job / hobby !
I have been looking at this design and wanted to make something similar (for mimo use on a mifi)
I found it interesting though you talking about milimeters (and your most certain at these frequencies) and using a digital meter going up to a 10th of a milimeter then ... I see your plying/folding looks far from being 'scientifically milimetric' ;-)
To counter this I was thinking to make this antenna starting from a mold (having ceramics experience) and cast it in aluminium. That way the material could be a lot thicker (thinking of the Kathrein antennas you dissected ;-) so in stead of a the 1.5mm I could triple the thickness (would that seem acceptable ? could it be even thicker ?)
The thing casting it in alumium is I would be able to make a more precise design by correcting it gently with the dremel.
Or would you have any better desing lying around for casting in alu ?
Might you have any thoughts ?
Thanks
JB
can i add reflector to this build?
@andrew mcneil i would love to see you do more 4G LTE builds and get some cheap 4G LTE Antenna from ebay and improve them so they work i got 4g lte 4g-antenne thats spelling on the box it works but the antenna in my 4g router work way better
Hi sir
I am from India
I live in no network (110 to 125 dbi ) network
Which antenna is useful for me
Andrew what about a Slim-Jim antenna for this band which might give a better signal and would be about the size of a large paper clip, That antenna is very interesting but you want a SWR of around 1.5:1
Hi David yes I have spent most of this week reading up on the Slim-Jim and I have big plans for it.
On Cuba in 900 to 1800 MHz can working?
Could anyone please confirm that magnet wire may also be used to build the antennas?
I was thinking that the enamel can act like corrosion protector.
It would work, note the enamel chips easily and flakes at hard bends quite often. Very narrow wire can also reduce bandwidth.
How did you figure out the shape of the antenna?
Thank you very much!
Спасибо за антенну. Попытаюсь изготовить.
Is it possible to build antenna that can omnidirectionally receive any type of frequency? If yes, can you make video on how to build it if possible?
No
Good job sir ...
sir Thank you very much for the knowledge you share with us. I tried to make a yagi from different calculators and nothing seem to work. Its so good to see the simplicity of your designs. please sir make something's as simple as this but with a bit more power for 1700 to 2100Mhz 4g lte range.
I have a few Yagi designs we can take a look at Shahid
@@andrewmcneil yagi's are highly directionAl and pretty unforgiving in calculations. do we have a yagi for 1800mhz here on our channel? searched but havnt find a video..am i missing something?
@@shahidiqbal9580 No this is the very first antenna I have made for this frequency.
@@andrewmcneil yeap ! and i am making it tomorrow and anxiously waiting for its larger sibling as well for 1800mhz 4g lte.
There are some good Yagi calculators around. www.vk5dj.com/yagi.html
Nice built but where’s the results? And this is only for those LTE modems like you can’t put that in your lightning port on your iPhone
Thanks so much sir
This is a system of dipoles at different frequencies.
С присущей диполям диаграмме направленности?
I would be nice if you combine it with cantenna
Great !!
Is it possible to modify this to work for LTE band 20 ?? ( Starts from 791Mhz )
Yeah,I'm also interested in that.
Just make all the dimensions 20% bigger.
Me too!
@@scienteer3562 i made one ;
drive.google.com/file/d/10tFIBSol7Qr0r0pAxra8a_EtyNddNF9O/view?usp=drivesdk
But it performed poor compared with my biquad,seems i'm gonna build a double biquad instead..🤔
thanks u so much sir,
I made one but it's not working 😔...
3g?
Do empedance matter of the antenna
Yes very much so
i need to overcome ~15 to 20 dBm, if this were much larger, would that help gain?
Hi Andrew, thank you for all the videos showing us how you make different antennas and how well they work! But for someone as dumb and lazy as me, I have a request (you can consider it a challenge ;-)). Can you fashion an antenna for 2.35 Ghz out of the garden variety TV coax cable, where I could just take a long piece of coax up to my roof, strip the outer cover, expose the center conductor, twist it (not too complex, because I lack even the skills you'd consider basic) into a suitable antenna and fix the coax to something (most likely a wall) and then get back into the living room and do the same with the other end. This way, no cutting, no soldering, no special impedance matching devices (I guess it would mean coiling the center conductor suitably without any special tools) etc. And we could make the enhanced LTE signal make its way into the living room with just a length of coax and some elbow grease (and your brainwork of course!). I eagerly await the McNeil Antenna! TIA.
Note that stock TV coax is 75 ohm. LTE cable is 50 ohm. It will work, but not well - also cable losses on TV cable will be high. RF200 cable is not overly expensive and will perform much better.
@@SimonShaws Thanks. TV cable is the most readily available. So, what would I need to do to impedance match the antenna to the cable? I am guessing a few turns around a plastic tube (length, diameter, no of turns?) and it would depend on the antenna too, wouldn't it? Then at the other end, in the living room, would it have to be a different type of antenna? Because it would have to radiate the signal in all directions, and again the impedance matching would have to be appropriate.
@@mohanvvip What you are asking is more than can be answered in a comment on a UA-cam video easily. You want an antenna to an antenna? Normally you would go antenna to receiver/transmitter.
Make 2300 -2400 mhz only antenna please 🙏
I am 5 kms away from tower and the signal is very poor. I will try this, thanks sir!
You better post a video
