I'm choosing what antennas I need to attach to my RV-9A, and that lead to ADS-B...of which I'm still confused. I've read the FAA webpages, the wiki article, but their information tends toward existing aircraft with legacy equipment. Thus I have this question:
For the many of us still building and equipping--no legacy equipment--and assuming I will want ADS-B In and Out capability--do I need a transponder on 1090 MHz? Or can I install only a UAT on 978 MHz?
