I picked up a Deans mini antenna (whip antenna) at the LHS today. The instructions say to cut the antenna wire from the receiver to a length of 4" - 10" from the receiver. Is there a benefit to cutting the wire closer to 4" or closer to 10", or does it not matter? Also, I'm mounting this antenna on a Raptor 50 and am wondering where some of you have mounted your whip antennas on your helis.

Thanks for the information!!!

somewhere in the middle is fine. They're
not that sensitive.

Besides, if you cut it short and screw it
up, then you're really SOL.

z11355, thanks for the reply. I figured that would be the best bet or cut the wire to the length I need to mount the antenna plus an inch.

Just a note, if this is the antenna that says to install the gold plug onto your rx wire, you may want to go ahead and solder.

After some speculation, I think that my whip antenna became a problem because the plug was not making the best contact. I went ahead and cut the plug out and soldered the wires together (after routing properly) and I removed a glitch problem... Just a thought to include with your installation..

This was on a 30-size heli.. Now I just leave the stock antenna on the RX..

Tom, I never use the plug. I've always prefered to solder the wires together. Just one less thing to go wrong.

Thanks for all the help!!! I didn't think about soldering the two wires together and agree that is a better idea!

I actually use the gold plug for my Revolution Whip antenna. It also saved my RX and whip when I had a very hard landing this last weekend. Tail rotor flew off like a bullet after hard Piros. When the bird hit on the skid, the plugs pulled out at the plugs instead of the RX. Just some food for thought.

Don't forget to mount the antenna vertically.
I know some say this is not necessary but if you do a range check there is a significant difference.

Why do we fear change, one of the two certainty's in life

Kino, thanks for the tip. I noticed it in the instructions but figured the physical position of the heli is always changing so the antenna will only be verticle some of the time anyways. I'll check that out just to be safe. I looked in your gallery and never thought about mounting it that way. I may try something similar. Thanks again!

Herc, Kino, that's why I bend mine 90º down at the front, just so the antenna "sees" a better signal. The ONLY Deans issue I have ever had, in almost 20 years of using them, was on one helicopter, with ppm receiver. When I was nose in and close, and I pointed the tip of the transmitter ant. at the tip of the heli's ant. , it would glitch. PCM receiver solved that issue, if you can call it solved.

Al, I mounted mine tonight. I did it the same way as yours, with the tip curved down and the base mounted in the same location as yours. I went into the galleries and found others who had mounted it similar to yours and there really is no other nice way to do it and keep it under the canopy. Thanks again Al!!!
