Has anyone tried building a 1/2 wave coaxial sleeve antenna for 40m? I
have
a large tree with a branch at 70' and i thought i'd pull the antenna up
with
a rope. Should i make the sleeve out of copper pipe? A 1/2 wave vertical
would be a nice antenna for 40m and i thought a coaxial sleeve antenna
would
give me a great feed impedance. Any thoughts? The coax are 100' of RG8.


There was an article in, I believe QEX just a few months ago. The
author made the "sleeve" out of several wires, hanging down, around the
coax. They formed sort of a skelton sleeve. It was for an HF band too.
