Happy Easter everyone! We have a IS-28B2 Twin Lark which we use quite a bit for instruction, it is good for spinning and intro into flying complex gliders (flaps & retractable gear). It is due for a complete overhaul which will include a new radio with a repeater control unit in the back for the instructor.
Since weŽll then be re-working the whole radio install anyway I have been considering doing something about the dragmaster factory radio antenna that looks more like a car antenna installed ontop of the fuselage tail boom.. For you experts out there what would be your recommendation for an interior radio antenna install (or a low drag exterior install) in an all metal glider like the Twin Lark?
Many thanks in advance,

Depending on the material your current antenna is made from, you might
try a tubing bender.
The radiated power from a whip antenna comes disproportionately from
the "bottom" quarter, which is why this works. It's still ugly, but
the drag is much lower.
