SGS 2-33A Form337 for Radio/Transponder

[T[_2_]]

We are looking for any existing Form337 to install a battery driven
electrical system in an SGS 2-33A. We are tucked in close to Class B
airspace that is about to expand in the next year and feel a
transponder would be a great idea in all of our gliders. We've been
using handheld radios for years, but no one has made a handheld
transponder that I can find.

Thanks

A handheld transponder would be an extremely bad idea !

Get a TRIG transponder, Mode S.
Put a stub antenna somewhere in the back pointing
down aft of the gear, with ground-plane above and inside.
Use the proper and expensive coax for the antenna;
this is not a radio shack nor shade-tree job.
Really best to get a proper radio shop to do the install.

Can't help you with a 337 but a good radio shop can.

Hope this helps,
Best Regards, Dave "YO electric"

The problem is that the "good" radio shop won't want to do install
without having "approved data" to follow.
Schweizer needs to do a modern battery installation drawing for folks
to follow. The existing one is for a lantern battery.

Just kidding on the handheld, YO.!
We are looking at the Trig units for the fleet, and roger on the
proper coax. We have experience within the club in that area. The
issue is an approved electrical system and battery box for the 2-33.

The Canadian Air Cadets have equipped some of their 2-33's with
transponders and they are real sticklers for doing everything
according to the regulations. Although the installation certification
they got would have been with Transport Canada it would probably be
useful to as a reference when you're trying for FAA approval.

The Air Force Academy 2-33s were also equipped with radios. Civil Air
Patrol has some of them now. Perhaps contact them? They were all
civil registered so would have needed FAA paperwork, one assumes.

As opposed to military aircraft, which are not usually certified, or
military pilots, who do not necessarily have certificates!

Good luck!
