I had to indulge my inner electrical engineer and mock up the VHF comm (right), Mode S/1090 ES ADS-B transponder antenna (left), and ADS-B UAT receive antenna (center/forward) where they’ll be on the fuselage.

These very nice antennas are all products of Don Pansier at Delta Pop Aviation.  Don specializes in non-TSO’d antennas for the experimental market, and measures each antenna’s performance to ensure it meets spec…very cool.
