For the past year I have been frustrated with poor radio reception/broadcast with my Terra VHF. Finally decided to go with a Trig "package" ( TY91, TN22, Tn72, TA14, TA50) . Installation was done at M & M Aviation (KMNM). Biggest issue was removing the rear seat and creating room for the technician to do his job. So far, it is a significant improvement over the old radios and intercom. Nice to have ADS-B out. Transponder antenna is mounted on the access panel in front of the tail wheel. Attached photos show the balance of the install. Radio cost via Spruce and local shop - just under $5,000, Still waiting on the install bill - will post when I get it.
