Very nice! I love the compact and inconspicuous form of this one! I don’t imagine it would beat a more directional antenna for anyone that’s more than a few blocks away from the local tower though eh?
Andrew, love your videos. You are very knowledgeable on the subject of antennas. I noticed on my dji phantom 3 advanced controller that the panel antenna measures 52 ohms but the omni measures open.. i saw your yagi design and noticed that the coax shield was on one side of the loop and the center conductor was attached to the other side of the loop creating a short. Wouldn't this burn up the transmitter output? I haven't seen impedance or open resistance and the effects on transmitters explained anywhere on TH-cam. Could you help us out? Thanks
I love watching the builds. But I have no idea what you would use the aerial for. Any chance of you showing how you would actually use the great device you built? What use is it to my mobile phone? Or am I just dumb. Thanks Andrew love the content!
I made a pair of Double Bi-Quads for Band 3 ( three mobile uk) which give 100% signal level, and RSRP -83dBm ( mast states max RSRP is -80dBm) Mast is 2 miles distant with Urban housing ( terraced streets ) between me and it. ! the pair is located indoors on top of wardrobe in bedroom. I want to make better quality version for outdoor location. What is the "recommended" spacing between the two antennas located side by side, Please. Will also need this sizing, to look for suitable enclosure such as you have on the video.
@@testports3216 It is a simple antenna to build.... and cheap too !... worth a try... you might be surprised at how good it is. Make sure you point it towards your nearest Cell Phone Mast... You can find that from a site called CellMapper - gives you the choice of supplier and the bands it transmits on, and which direction it beams to.... Try to use a compass bearing to get the strongest signal at the antenna.
Could you possibly build one in the 1.7 GHz range and arrange them four-sided and one on top so that you get an omnidirectional antenna tuned to weather and slightly angle each of the four slides up a little bit? Do you think that would be enough to have a nice portable weather satellite omnidirectional as opposed to a large qhf Helix which I've actually built one and it's quite large and boldly to carry around would one of these be a nice portable alternative and could you get enough signal you think quite easily?
@@TuttleScott I know that. Do they have cellular towers in England that use 2.4Ghz and 5Ghz?? Or, put another way, does anyone there sell service using those frequencies?
@andrewmcneil Really good. What would be the reflector to element set-off to center this around 2.3 Ghz? The tower I am connecting to presently is using that instead of 2.4 or 2.7.
@@DNF-Rejak who is the cellular provider for that frequency band? I use AT&T in central Oklahoma and they are using the 850Mhz band. Get better range at the lower frequencies.
Can't believe I have never thought of this before!
Andrew I hope you are doing well, we want the antennas frequency range both GSM and 2.4Ghz as your Horn antenna.
Great to see you back Andrew!
Sir please suggest 2300mhz antena daigram plz plz
from oran city algeria contry i love yr chanel andrew thanks man
Your welcome
You are so creative, I love your methods.
17:30 Excellent work😊😊
Can you make a review of the radio wave detector?
Thanks 🎉
What is that?
A crystal diode can be adopted to be a radio wave detector.
Very nice! I love the compact and inconspicuous form of this one! I don’t imagine it would beat a more directional antenna for anyone that’s more than a few blocks away from the local tower though eh?
even though its sealed I still like to put drains in the bottom of outside stuff cause water will find a way.
It does
Is it an isolated ground with the main driving element?😮 Wow
No
Really good video, would be great to see one like this on 2.4 and or 5.8ghz.
Coming soon!
Built the sardines can biquad some years ago I did.
Still in my collection!

Clever.
850mhz band would be my best option for GSM as signals pooh in my area.
Was the same here a few years ago
Might be able to modify an old UHF tv yagi for 850 mhz. I’ve had good performance from one I set up for 750mhz band 13 and it was super cheap.

So, change the lengths and size of the ground plane and slightly angle the four side panel up a bit and have one mounted facing straight up?
Very cool

I don't have indoor signal.outdoor have 1 bar can i increase signal using this antenna

is it okay that the pieces are not perpendicular?
😊😊
Would a triquad be impossible?
So basically you would have five antennas that you're connecting together to face all the directions and above?
Why do you call it a “4G” antenna?
for 4g cellular network probably.
@@TuttleScott Here in the USA 2.4Ghz and 5Ghz are not used for cellular.
