Hey Guys, Has anyone experimented with feeding both a horizontally polarized and vertically polarized antenna simultaneously on HF? Such as, feeding a horizontally polarized yagi and a vertical on 20
I haven't done that, but I have done a fair amount of A/B'ing of a 20 meter ground mounted vertical vs an inverted vee at 60 feet. More often than not, one is better than the other, but it's equally
Gentlemen, I am using circular polarization on TEN meters, using a 4 element quad. Loops acting as parisitic elements "don't care" about polarity, with NO polarization attenuation. That's another rea
Interesting writeup, however, I'm not too sure about your statement: "In as much as a the receiving station benefits from diversity receiving antennas, the transmitting station reciprocally benefits
Gentlemen, Thanks for your interest and comments. Sometimes it improves the received signal on the other side... sometimes no difference. Most say the QSB fades are less severe, never eliminated of c
This experimental data may be of interest: Friday night I did a bunch of A/B tests between an 80 meter inverted vee, 120 degrees apex angle, 60 feet apex height versus a voltage fed vertical. The ver
Note on Vertical vs. Horizontal polarization. It is not just a question of polarization of the signals, but the difference in the radiation pattern. Similar antennas, similar heights but different po
TT: I have seen similar performace differences on Topband between my shunt-fed tower with seven radials and my erstwhile 160M inverted L with a half-mile of radials (!) and the vertical element 45 fe
Correction. It's current fed on 160 and voltage fed on 80. Rick N6RK _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather St

I don't know about TA, but HFTA, in the latest ARRL antenna book, says that it only handles horizontally polarized antennas, which makes me think that it doesn't deal with polarization at all, but j

Good question. The signal to noise ratio on the inverted vee was sometimes the same as the vertical and other times was better. The vertical was never the better receive antenna. In the past, a 40 m
Fascinating question in it's implications. If the atmospheric noise (which, particularly at night, might not be the dominant source) were uniformly distributed (source direction/polarization) then th
