I think 1st thing I would do- cuz it's easy- is to simply test the radio against
a known good one. Find a buddy, maybe most anyone at the airport on Saturday
morning, find out how your radio works without the plane involved. If you don't
have battery power I imagine you can plug into a car's 12v acc. plug.

Richard and all.
There was a time, when I had my Amateur Radio license, that I knew
something about radio frequency propagation...not now however...but I
dug up this design from the web...looks easy and is an inverted V which
simulates a half wave antenna and requires no ground plane....Herb

Dee, One thing to remember about antennae. Electrical ground and radio
ground plane are not the same thing. I mounted my homemade antenna on the
top of the nose cone with a six inch diameter piece of .025 aluminum inside
the cone as the ground plane. ICT tower could hear me loud and clear as
soon as I had line of sight from 28 miles and I could hear planes in the
pattern at McPherson over 60 miles.
When I flew the "plane from hell" home I had the same radio but with the
rubber duck attached. Salina tower could not hear me at 6 miles.
The best place to get antenna advice is a local ham radio operator or club.
Someone is almost sure to have an antenna analyzer that will help you tune
your antenna for optimum performance.
Another good source is the Aeroelectric Connection right here on the
Matronics Forums.

I have an Icom radio with external antenna under the fuselage cage. It is attached
to a aluminum plate which also acts as a foot rest for the passenger. Works
great and I can pick up transmissions from 50+ miles.
My biggest problem was interference from the 912s engine. I bought a couple bags
of chokes from Radio Shack and put them around every wire that I thought might
cause a problem. Problem solved. Not sure which wire was the problem as
I didn't take the time to test each wire separately.

Subject: | Re: Handheld Radio Performance Issue |
I am currently installing an external antenna at the end of the wing
(underneath). I did try the radio with the rubber duck antenna that came
with the Icom A6 while on the ground and that provided a strong clear
signal. I'm not running on ship=99s power yet; using ICOM A6
battery and a 9 V battery in my intercom. Question: what is the
function of a ground plane at the base of an antenna? I do have room to
add a ground plane if that will be beneficial. Also, is the orientation
of an external antenna important? RSVP
Thanks for all the advice,

These looked like lil transformers with two wires? Or were they toroids? How much

effects the radiation pattern on both tx and receive. for best results the
ground plane should be 1 to 2 times the length of the whip in
diameter. it could be made of very thin metal,,, or could be 3 or
more wires, like the spokes of a wheel. each between 1/2 to the length of
the whip.
