Which antenna is perfered for ADSB, Transponder or UAT?
Antenna Information
The SV-ADSB-470 requires its own antenna; it cannot share the transponder’s antenna. The selected antenna should be installed according to the manufacturer’s instructions. A UAT-specific antenna or a transponder antenna may be used with the SV-ADSB-470. Antennas available include (but are not limited to):
Delta Pop (non-TSO):

Rami AV-74 (TSO’d):

Also, any antenna suitable for use with an aircraft transponder will work with the SV-ADSB-470.
The ADS-B antenna must be installed at least two-feet from the transponder antenna.
You're probably referring to the $21.75 TED transponder antenna, Aircraft Spruce p/n 11-17995:In general, the $14 transponder antenna from ACS is always a good choice.
For those of you with plastic airplanes, you might look at the Advanced Aircraft Electronics (http://www.advancedaircraft.com/index.htm) transponder antenna. It is $99, but seems to work OK for transponder use in my plane. I have set one up in my wingtip for ADSB, but have not yet had a chance to use test it. Be aware long coax runs may require more expensive low-loss coax. Plane is in FL, but I am currently in NC. Hope to test it in a few weeks.
