More turns gives longer range, but narrower beam. 3 turns gives a wide area at short range, 6 turns is really narrow beam, but long range. 12 turns is like a laser, super narrow.
Why that gauge? IBCrazy recommends 10 gauge. From his post at RCG "Wire - the thicker, the better. 14AWG is fine. 12 or 10 AWG is better. 1/8" or 3/16" copper tubing is supreme!"
I see a lot of people using 6 turns- is there a reason for this? Also, if I would like to build a 6 turns- where can I get the plan for wrapping the wire around? Thanks for your help good sir.
Why don't you give detail instrutions other than wire size ? what about the galvanized tin metal thickness and dimensions , the dowel rod size , and ay other pertinent info . 14/2 wire is very soft and bendable . How does the antenna coils keep their shape ?
I ran into that problem too. I bought a 5/8 dowel. Dowloaded the template from flight test and the sides dont' match up when I wrapped it around dowel. Any luck with yours? I really wish I had a cnc machine!
hi is very good , can you make a video how to make it for ( 4G multiband MIMO ) sorry for my bad english ( 700 MHZ TO 2700 MHZ I guess you have the right idea,,

it dont matter how thick the wire is, the thicker the more bandwidtch...the thinner, its still in tune but smaller bandwidth...
I use 14 gauge wire which is 1.63mm diameter wire. You want to use wire as close to that as possible.
From rcgroups thread IB_Crazy listed these gain figures:
Gain ~ 4.5 + number of turns (3 turn minimum, 12 turn max)
3 turns = 7 dbi
4 turns = 8.5dbi
5 turns = 9.5 dbi
6 turns = 10.5 dbi
7 turns = 11.25 dbi
12 turns = 12.5 dbi
Great video, thanks for sharing.
otimo video simples e objetivo !!! qual a altura do fio positivo para soldar no espiral ???

Isnt the dowel rod a little to large. the guage does not wrap all the way around.

Very nice video, any idea what the gain is and have you got some flight footage?
is there a specific size wire that we need to use for the 5.8 ghz?
Maybe you should just put the URL of the link on flite test...

how do you get a mile away? What kind of receiver and transmitter antennas(from your radio control) do you have?

( 700 MHZ TO 2700 MHZ I guess you have the right idea,,
how do i know how many turns to use?
theres any cumputation??
Impedance???? I dont see the right adaption and is crucial (50 Ohms?)
trap isn't necessary for 5.8ghz, but it is if you are using lower frequency
Argh! Helical! Not Helicoil! Sorry. Just needed to say that. Thanks for the video.
Do you run cloverleaf on the transmitter? 3 or 4 leaf?
So don't need a wave trap
no wavetrap?
