What's the roofline of the hangar look like? Most metal buildings have gaps
where the ridge cap covers the roofing (easy to run an antenna cable
through). A 4" black spike on a magnetic base attached far from the edges
of the roof would be out of sight from the ground, and virtually invisible
from the air. Biggest trick would be getting it up there without being seen.

Not doable either... and can't get up without being seen. Roof of a row of T-hangars
is pretty flat and in proximity for observation.

100% understand. I found that all I needed to do with mine was to raise it a few
feet on the interior wall of the metal t-hangar to get adequate reception. The
fire-resistant dividing walls in the hangar are sheetrock attached with screws.
The magnetic base of the antenna grips one of the screw heads about 10' up
& very close to the sliding metal door. It's inside, so no one is the wiser.

Can you get to the roof from inside, punch a small hole, in an inconspicuou
s spot, and feed the cable as Joe Gores described, out the hole. By the wa
y, if I were to make up this antenna I would finish it off with a piece of
shrink tubing long enough to cover the braid exposed on the surface.

Good ideas (to work from inside). The question is would such antenna lying flat
on the roof (horizontal) or one hanging down sticking to the wall work better.
