Glide Slope Antenna Ground Plane

If the fairing is aluminum, it will probably work quite well. If the
fairing is glass, probably not so very well at all. A few pieces of wide
aluminum strips from the original location to the base of the antenna may
provide you enough of a path to at least have some semblance of a chance of
working.

Oh, the smartass answer is that of course it will work. So will a wet
noodle in a copper septic tank, just not very well.

Sorry, it's not a GS, it's a Marker Beacon. The original antenna is a
Comant CI 164 mounted flush to the skin. The new antenna is a Comant CI
118-1. The flush mounting location for the original Comant is a very
convenient place to put an IR camera, useful for taxiing at night and in
poor visibility. I'm designing a fairing in which to mount the camera
with the antenna bolted to the bottom of the fairing because that's what
the customer wanted. I want to not look stupid if I submit this to a
radio DER.

Here's a picture.

Thanks, Jim. Since I also need lightning protection, I'll probably just
metal spray the whole thing
