Towertalk is definitely educational! I was also not aware of the way the
resonant frequency changed at low heights. I still see no point in checking
the SWR of an antenna near the ground. You can use an ohm meter if you're
unsure of your connections however it was an interesting discussion.

You guys are way above my head :-)
I had no idea the resonant freq goes up and down as the antenna travels on
its way up. I thought it just went up on a steep curve till about 15 feet
then gradually after that. I can see why some head scratching as we pass
thru the "decrease zone" "what did I do now" hihi
