Your point is unclear to me. Of course the pattern of a horizontal antenna
changes with changing height and with other environmental factors. If the
antenna is actually on the ground the efficiency is

You can never have too many antennas...
Unless they interfere with each other, a non-trivial issue.

thought it was a coax cap. I'm 61 and been around since early 80s I guess I'm

Yeah, but I'm not _that_ old!
I received WN6BIL from the Little Print Shop (they issued licenses back then,
right?) in June of 1970. ;)
I signed the resulting QSL cards as the "12 yr old OM."
