The sense antenna on our Cardinal broke right at the crimp connector
that attaches to the feedthrough insulator at the top front of the
airplane. This thing appears to be made of 18 gauge copperweld wire.
Since I still have the antenna and can pull measurements from it, is
there any reason I can't fabricate a replacement myself? Or does that
crimp connection have to be made with an aircraft-rated crimp tool?
