The TT21 has only just received its European approval, so there is very
little experience yet.

Playing with one on the bench, and making up a cable harness for an
installation, it looks good both for the installation and ease of use.
The documentation is clear, concise and comprehensive - a highly unusual
combination.

The two box solution means that the panel fit is easy, and the box that
does the real work can be positioned for a short co-ax run to the antenna
for minimum RF loss.

From my dealings with the company, I am impressed so far.

Thanks, Darryl - I'm much more educated now on ADS-B, TCAS, TIS-B and
FIS-B than I was this morning!

All I need now is input from anyone who has a Trig TT21, especially
with regard to ease of use and reliability.
