The same thing that happens at 15,000 feet. It will do want needs to be

done, but if you will frequently fly above 18,000' outside of a "wave

window", consider the higher power unit.

Eric,
Thanks for the link. I never knew SSF had its own website. I mostly fly in Northern UT and the Reno area so 15K on a good day is not unrealistic. I have no desire to fly the high altitude wave you mention. My question "What happens at 15,000" was mainly referring to what is ATC going to see on the scope. If the display on the scope (Or TCAS) tops at 15K then I may need to keep shopping. If this unit will display PA altitudes between 15 and 17K then, for the small amount of time I spend at these altitudes, this unit would probably do.
Just bought a new ship and I am in the process of setting up (Completely redoing) the panel so you guys may have to suffer through my silly questions for awhile.

The TC 20 control unit is the same for both the TT21 and TT22. The
altitude encoder is part of the TC 20 control unit.
