Thanks Vic, I get it now: the method that I am using is valid only when the
antenna is 1/4 wl or less. Since my EFW is 86 feet, it would only
be useful trying this comparison on topband where a 1/4 wl is roughly 125
ft. It was suggested off list that my best bet overall is to employ the
use of a field strength meter. Perhaps it is time to invest in one!
