[TowerTalk] OCF Dipole Questions

It should not matter which end is connected to the tree or tower as long as
they are insulated from them.


Where does it make best sense for the feedline to connect and be supported?

I have mine offset from the tower with a fiberglass pole about 5 feet with
the feedpoint at the apex and run it as an inverted V with no problems.
This way the weight of the feedline is supported by the tower.

The apex of mine is about 55' up.

If installed flat it would likely be as directional as a standard dipole as
far as I know.
