Hi all,
I also have a problem with such antenna:
This one I mounted today to the side of my steel-lattice tower with
32" face.
This raised the SWR within the band and put its resonance to
14480Kc (lowest SWR 1.1),.
Before, with a rotable pipe mast on the other tower the antenna was in tune.
When I retuned the two driven elements I was limited by the length of the
tubing,
so lowest possible resonance occurs now at 14360kc.
Since I guess that this shortening effect is caused by capacitive loading of
the element center by the tower itself, I wonder if using a small coil at the
center
of the two driven elements would cancel it effectively, hopefully not raising
the
feedpoint impedance.
Any ideas will be appreciated
