I have found that my transmit antenna is frequently better, but it is not
omnidirectional, and has 15dB of FB ratio, so antipodal focusing is
unlikely.... certainly the vertical waveangle of arrival is the key here, but
it is strange, and so far not analyzable... keep those reports coming in
folks, and maybe someone will see a pattern....
