Ok first great video! But I have a question about Attenuator? What is the purpose of a Attenuator?

Tahlula Rose commented on 24 Feb 2015

An Attenuator reduces the power in the signal, used to keep a strong signal from overwhelming a receiver circuit at times

+RC Model Reviews hey bruce.. i got a somewhat stupid question. i have a 3.3-3.8 ghz patch antenna laying around. can i somehow use this for 5.8 fpv ?

Tahlula Rose commented on 24 Feb 2015

the short answer is no, the antenna needs to be matched to the transmitted freq.

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 ?

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

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!

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 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!"

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.
