This is the manufacturer:

Wonder if they might consider adapting this thing to gliders?

Manufacturer link is actually: http://sagetechcorp.com/

Nope...the market is too small. I asked them at a trade show. It's
meant for UAVs. That market is small, too, in terms of volume, but
they can charge a lot...UAV makers are less price sensitive than
glider owners.

Other than a few thousand dollars, what's the difference between their
"conventional manned installation" and "adapted to gliders"?

This link should take you to their website.

The TT21 is a class 2 transponder and therefore *not* suited for
gliders. If you choose to go with Trig, then do yourself a favour and
buy the TT22.

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.

The TT21 is very suitable for gliders. Its being installed in many
gliders in the USA and I expect elsewhere. The issue between class 1
and 2 transponders comes down to a fairly meaningless difference in
output power when you compare 15,000' vs. the maximum altitude we
typically fly at. If the difference in price between say a TT21 and
TT22 puts anybody off who should otherwise be installing a transponder
please install the TT21

If you ever want to climb above 15,000 ft in an airspace where a
tansponder is mandatory (which I do regularly), then you are just plain
illegal with the TT21. This may be "fairly meaningless" for you, it's
not for me and should not be for any pilot.

If you want a Class 1 the best option currently available is probably
the TT22.
Here in the UK the possibility of flight above 10000' is very limited
Wales, Scotland and a few areas in the North of England and so
wouldn't be a consideration for the vast majority of owners.
