On my 40 meter beam I needed a housing for the gamma capacitor. I used about
18 inches of 4" pvc pipe and put fernco caps on each end. It contains the
variable cap and a motor to tune it from the shack. Hose clamps strap it to
the boom.
I drilled The rubber fernco caps with small holes for the cables to fit
tight. This keeps the water out.
A couple of small holes on the bottom side of the pipe for vents.
