Hello Listers,

I am at the spot in cabin construction that I need to finalize what I'm doing for antennas. I have two radios (Garmin & Becker) and a PMA 4000 audio panel all nicely wired up by Stark Avionics.

Do I need to install two antennas or one w/ a splitter?

Any recommendation on antenna. I have the cheapie homebuilder's special from Spruce, but am thinking maybe I should upgrade.

Thanks. Don...

Install 1 CI 121 on the upper fuselage, and a CI 122 on the bottom. Feed them with rg142 or rg400.

The short answer is two antennas... Especially if there are two transmitters.

You can use 1 antenna for 2 radios, contact Bob Archer of Archer Sport Antennas, he has a very nice switch box that is tied into the key line of each radio, effectively switching which radio transmits through the antenna. It's also setup to receive on both radios. BTW, it's about the price of an antenna, doesn't save any money, but clean-ups the airframe.

Part number SA-010

Check this link : http://home.hiwaay.net/~sbuc/tvrvbg/PRODS2.doc

Phone number : 310-316-8796

Good luck!!!!
