ATC Antenna selection
« on: November 08, 2011, 05:15:50 PM »
Thought I would share my experience with air-band antennas.

After dealing with a "Ham" repeater (W8DZ) blasting away at a KCVG tower frequency, I finally ditched the broadband "scanner" antenna and finally made the transition to an ASP ground-plane antenna cut to 124MHz center frequency, bandwidth about 118MHz to 128MHz.  It is so out-of-ham-band, the Ham radio is no longer a factor.

If you listen to the KCVG feed now, it is fairly pure and clean.  Not so with a number of others. No buzzing ground-loops, no RF interference, no static on most transmissions.  Judge it for yourself after a listen!

The ASP antenna was about $160, so not cheap, but works!

Jerry,

FWIW - I don't know what it sounded like before, but it sounds great now.

Hmm I maybe having a similar with the SAT feed. There's a HAM store with an array of antennas literally down the street from my antenna location. At times I get clear transmissions from airborne aircraft but rarely from the Tower or App/Dep.

As with any problem, just gotta keep throwing money at it. heh
