Default Question on JR-Futaba buddy cord

This cord, which is very nice for our club's instructors to have, requires that a Futaba buddy box be turned on (for gimbal power?) when connected to a JR master box.

Since my normal buddy box has no battery in it, I decided to use my 8U as a buddy box for a recent student (who had a JR setup). I pulled the frequency module from my 8U, and everything worked fine (sure enough, it worked only with Futaba buddy box powered up). Later I wondered...

I have heard/read that when your transmitter is on, you should have the antenna extended at least one rod to avoid burning out some part of the RF circuitry. In this odd circumstance, though, is it necessary to extend the antenna even though the frequency module is removed but with power on?

Ah, no . . . you can't protect a transmitter that isn't there. When you pull the module, there is no RF deck left to protect, or for that matter, anything connected to the antenna.

Thanks, Tim.

That's what I thought, but I just wasn't sure if there was still some power making it to the antenna somehow. Thanks for the confirmation.
