Subject: Re: Kolb-List: Icom External Antenna
I've got an icom A5 and would like to get an external antenna that I can mo
unt on the belly of my Mark3. Anyone out have any good recommendations?
my dipole center is at the left side bottom of the nose cone, the center w
ire goes up the left side and accross the top. and the braided wire angels
back on about a 45 deg under the floor. the position was selected to gi
ve the best swr, and both wires were cut to give the best swr's. way che
ep, way easy, and nothing sticking outside to get bumped or bent. one watt
radio will talk 150 miles plane to plane. the signal report was good sign
al but with some background noise. last week i had a hard time talking t
o another plane (super cub) in the area,,, but one of the fbo's who was
further away heard me ok and relayed to the super cub. made me think the r
adio setup in the cub was not up to par. he could hear the fbo but the
fbo is putting out 15 watts.

For a 1/4 wave antenna in the VHF Airband (118.0-136.0 MHz) about 20" will put
you in the middle of the spectrum (127.0 MHz).
Good luck.

One other item I'd like to find out is the best and maybe easiest way to
suppress ignition noise. Is it necessary to go the full gamut and use
resistor plugs, cap, and ignition lead shielding? Will strobes also add
to the noise?

Thanx G.Aman
i started plenty long.. i think about 25 inches, on both legs, the
inner connector, and braid... my ham radio club has an antenna
analizer, and i used it to figure the final legnths... i will have to
measure the next time i go to the airport.

Thanks Boyd,
I wondered if I could use the same SWR meter that I had for CB?

Frank,
I'm fighting the same issue with the Jabiru.Resistor plugs made no differen
ce.Shutting the engine off helps the most.

You can use resistor plugs, OR resistor caps. Use both together and you
can fry your ignition. Shielding always helps. For me, the combination of
resistor plugs and the "ANL" setting (automatic noise limiter) on the radio
is all I need. Strobes can add noise, but I don't notice any from mine.

>>>>>>>>>>>>>>
i am doubtfull.... cb is around 50 mhz,,, aircraft centers at 127
mhz,,, i dont think it will cover that mhz spread.( check the owners/
tech manual)
check arrl.org,, and see if there is a ham radio club in your
area,, can probabley get some help for free.
