What are the consequences of having a Trig 21 vs 22, in both the TABS regulations and pure functionality? I understand that a Trig 21 may not meet TABS regulations, if there ever comes to be some. But will it actually function, if wired to the Trig TN72 source?

I would think either would be fine. They are almost identical except in power output. There are actually no TABS regulations other than the TSO.

goes on and on about UAT and TSO-166 specifications but doesn't mention TABS.

We will see when more information comes out of Trig. For instance - It would be really nice if the required antenna wasn't larger than the TN72 and more expensive.
