Best way to feed a vertical?
I need to re-erect (after major house remodeling) a 33-foot flag pole
(also known as a 40-meter vertical) and would like to know the best
way to feed it.
Prior to the remodeling, the base of the pipe was held a few inches above
ground and the antenna was fed by simply connecting a 50-ohm coax shield
to a ground rod (with radials, etc.) and the center conductor to the pipe.
I later added an inductor (from memory: maybe 30 turns of B&W with a
diameter of maybe an inch and a half) from the base of the antenna to
the ground rod, hoping it would discharge any static electricity that
might build up. The inductor changed the tuning a little bit but I
never saw any other differences.
Any suggestions?
