For a Standard category glider it was a big pain to install and get the

For me, the documentation was trivial. I made a logbook entry and got a PAPR https://adsbperformance.faa.gov/paprrequest.aspx (recommended but not required) The TT22 antenna got moved to a more optimal position further back in the fuselage, so I had got a fresh transponder compliance check (which was due anyways). My avionics tech looked over the installation that I did.


It was also very expensive

The TN72 including an interior mount antenna cost ~$400. I also bought a custom length antenna wire for the XPND for a few bucks. Craggy made the interconnect cable for me. I had a fun 5-6 hours doing the install. The transponder was installed by the previous owner.


WAAS GPS box is very large, nearly double the size of the XPND remote box.
