I did this some years back for Field Day and found it worked great.  I had a 
2M J-pole made out of copper plumbing pipe.  The pipe did not have caps on 
the ends, top or bottom.  I threw a rope over a tall tree (oak), using a 
fishing rod (big one, surf rod), ran the rope through the copper pipe and 
hauled it up to near the top of the tree.  I was able to keep the vertical 
"right side up," and the coax coming straight down from the feedpoint.  I 
think hanging it "upside down," could work too, assuming your antenna wasn't 
quite like the one I had that lent itself to right-side-up hanging.  You'd 
have to be more concerned about keeping water out of the coax and connector, 
etc.

Putting an antenna up in a tree like this in many cases gets the antenna up 
higher than any other tower or support you have handy.

Or, make the vertical out of wire and insulators.  Cheap and, if made right, 
should work just as well as a commercial antenna.

Subject: [TowerTalk] Vertical in a tree


I am thinking of dragging a 2 meter collinear vertical up in a tree.  I am 
under CC&Rs like many of us and just cannot make out some of the group on 
simplex that I like to frequent using the vertical or the 4 elt beam or 5 
elt quad in the attic.  The tree would be somewhat higher than the attic and 
the antenna would be camouflaged by the tree.

My questions concern suspension and "insulation".  The main portion of the 
antenna is wrapped with something except for the stinger.  I would probably 
need to insulate the stinger at least from branches but how?  Electrical 
tape, neoprene tubing?

What about suspension?  Egg insulator at the tip with nylon cord somewhat 
like a wire antenna then insulator to suspension cord?

Thanks es 73, de Jim KG0KP
