Re-installed the IFR GPS antenna in a new location
Today I relocated the GPS antenna to the top of the aircraft, just aft of the rear window. I planned on installing it on the canopy glareshield, however right before i drilled the holes in the glareshield I tested out the GPS and it wasn’t working. Turns out there is a minimum antenna cable length of 6.5ft. The coax cable length was only 3ft to install it on the glareshield. I also didn’t like the idea of having a big white antenna obstructing the nice view out the windscreen. Unfortunately it was an expensive mistake. The crimp on connectors on each end are $27 a piece, plus $2.75 a foot for the cable…ouch!
Antenna aligned with the airstream

I fabricated a doubler plate with nutplates riveted in. I designed this so that the antenna can be installed or replaced without having to climb into the aft tailcone.
