Posted: Sun Oct 22, 2017 9:02 am Post subject: Nav antenna |
|
|
Does anyone have a nav antenna (of VOR/Glide slope/Loc variety) conveniently to hand so that they could measure the resistance across the pin to sheath, or maybe is clever enough to know what it should be? Am pursuing a glitch and find that my nav antenna has a very low resistance unlike Com & Transistor antennae.

The are horizontal dipoles and should effectively be open circuit.
