Good way to burn out the front end of the NavTex Receiver.....

The navtex is fine. The guy selling the switch gives written warranty
on any damage to the receiving part of the navtex and the firm has
been around for a while. He designed 4 mechanisms / defense lines to
prevent voltage / current to pass to the navtex. But maybe you're
right and is it too risky.

So, now what, I'm restricted to a passive antenna for the navtex. What
do you think of a whip on the radar arch for the navtex. It would be a
bit close to the backstay, some 4-5 feet.

TIA,
Len.

The backstay will give SIGNIFICANTLY more static to the receiver on 518 Khz
than the appropriate loopstick I mentioned earlier. The loopstick antenna
mounted on the handrail is a MUCH better antenna for NAVTEX than that
backstay, it's really cheap and easy to install.....so why take that
chance? Doesn't make any sense.
