As far away from your 'noisy' gas engine as you can.

As far away from the sparkplug as you can get it.
Most I've seen use a base loaded whip mounted in the front of the heli and pointed foward. I wound my original antenna on a piece of antenna tube and mounted it so it is inside the canopy on my raptor. Haven't finished the gasser yet but, will do the same to it.

What Bushy said goes double for me. I use a Revolution base-loaded whip mounted as far forward as I can get it and pointing forward as well. Folds nicely under the Intrepid canopy in a gentle forward curve.

As stated above, keep it away from the plug AND magneto.

Also try to find a spot where it is away from the battery and electronic devices..servos, etc.

This may sound limiting (it is to an extent), but I have often used the forward side frames....a location which nicely isolates the antenna.

Best Regards, Dario

Bushy, right about to place the aerial as far as you can from the engine plug or IG but are you sure about what your doing with your aerial? I m not electronic eng. but as far as I know this coil disposition gives you the same receiving capabilities as cutting the original one to the showed longitude (1/3?) not a good idea imo.

Bushy,
Elossam has a very good point. You are definitely decreasing your range by coiling the antenna. Get the proper equipment for your gasser.

After 30 years as a communications tech and amatuer operator, I fly 50mhz ham band with a range check that's good to at least 100 yards.

You buy the base loads and I'll make mine.

May be you have loaded your antenna to keep the right impedance. Even so the base loaded antennas have its range reduced. I f you take a stock antenna and coils it as shown without any other modification the result will never give the same range, thats sure. If you´r happy with it, go ahead.
To have enough range or to have the best one I can get is very important because its also safety question.

I placed my RX full back and extenden the aerial to the tail fin as far as I can also from the tail boom. 95% of my antenna is extended; Not so pretty but functional. Tested also using PPM receivers instead of PCM and never suffered a glitch.

non base load

I run mine through the frame by the clutch and drop down low to the boom supports like a guy did in Ca. The antenna is in a yellow plastic sheath from say hobby town that the airplane guys use. Put three zip ties on this sheath toward the end of the antenna and three spread out on the tail boom support. Cut the zip ties to 1/5 " nubs and space it with some tight fitting yellow or what ever fuel tubing that slips over the three zip ties and keeps the antenna snug yet away from the boom supports. this keeps it clean and gives maximum range.

Hi all,

I have just recently hovered my Predator gasser SE. I have stock antenna runs down (from the nose) the right side along the top part of the frame straight along the boom. I have the boom mount servo so antenna runs along servo and servo lead. Actually sounds like I am doing it all wrong. I have done a radio check with engine running from side and front seems ok. I see others are using a base load antenna seems like a good idea.
Heliproz sell this little gem Revolution Whip 72mh RVO1010 72 MHZ. is this money well spent or is there a better option?

Cheers
Randy
