Concerning the SteppIR on top of the tower and its effects on the
half-sloper and inverted V. I can see very little interaction. The beam
elements are not connected to the boom, so any "top hat" effect is due to
right-angle coupling (which I expect is very little). Both the inverted V
and half-sloper have SWRs mostly in the 2:1 to 3:1 range where I operate
(which is fine for me) and any changes due to SteppIR manipulation are very
minor.
Unless very long coax runs are involved, I always wonder why so many people
are chasing 1:1 matches on the low bands. My "high power" is only about
700-800 watts, so I may be avoiding some of the effects of a poorer match.
