The TT21 is a class 2 transponder and therefore *not* suited for

Please explain your reasoning for this statement. This seems to be a
minority view, at least in the US.

Class 2 is only 'legal' to 15,000 feet. The extra wattage of a class 1
is 'legally' required to fly above 15,000. Frankly it doesn't make any
sense to me. In my limited experience, the higher you are, the
greater the range of your RF device.
