Hi Jim.
Thanks for the reply. The answer is simple. Convenient! A pair of trees are there, about 100 feet apart and between them, nothing.
No balun used. The ends of the dipole are away from each tree by at least 20 feet. So its pretty much floating in space except close
to ground.
The ground is clay and can be damp at times. I cut the wire lengths wrong the first time and swr at 7050 was way off. Remeasured
and sure enough I was off by more than 10 feet! Cut a pair of 5 foot wires, twisted them in place, done. Hung the vna in the air with a
couple of gator clips, done. Coax back to the shack.
Although NEC says this is a zenith burner, there is still reasonable gain at say 45 degrees off horizon.
