Default Antenna and Coax Length

It is an APIS. The antenna is in the trailing edge of the rudder due to the
fuselage, vertical stab, and most of the rudder being carbon fiber.

I do have an inexpensive VSWR meter. I also have a 50 ohm dummy load (left
over from thin wire ethernet days....). I'll check my meter with that.
I haven't installed my Microair radio in the glider yet. I did a check
after installing the wiring and connector using my handheld ICOM and the
VSWR was a little less than 2 then. Looks like I should be okay.

Hi John:

Remember that your dummy load may not have the power rating of your
Microair. I think your Microair is rated at 3 watts carrier and your dummy
load may only be 1 watt. That will still work - but keep the test
transmissions short - enough to get a useful reading. 10 second or so
transmissions should be fine.

Colin
