Maybe you could call it a vertical C instead. There is some confusion here regarding vertical and horizontal polarization and the V height. Ace is being physically descriptive and Jack is talking about the electric polarization. I have not looked up the efficiency but I expect that the V is more lossy for transmitting and that does not apply to receiving. The angle for receiving will affect the angle of reception though. Telamon, If you can figure out why dxAce would make personal attacks on me while we were having a polite discussion about antennas, good luck. I quoted his misunderstanding of the original poster's comments three times, and that poster even verified I was describing exactly what he wanted, while dxAce was not. Ace never envisioned a "vertical dipole" such as you gave him an out for above. Nor was he trying to compare polarization of any kind. He just can't read or listen today. Nor does he understand what lossy means, such as an inverted-vee can receive much better than it's lossy transmitting, nearly equaling the horizontal dipole in most reception but falling far short in transmitting compared to same. And all center-fed dipoles have small bandwidth, but of course they work well with a tuner above their cut frequency. I replaced an inverted-vee with a horizontal dipole years ago, and the same antenna horizontally can do with 125 watts that which took 1,000 watts to accomplish with the vee. The lossiness comes mainly from the antennas ends of a vee approaching far to close to the ground. The horizontal dipole at minimum 1/4 wavelength above ground is about 80% efficient. At 1/2 wavelength is it over 90% efficient, even over lossy ground. But receiving has nothing to do with the ground losses from transmitting from a dipole, and poor Ace is determined to dig himself into a deeper and deeper hole on that simple fact. And you still haven't a clue... keep on promulgating your crap... though it does indeed have a sense of truth to it. Still waiting for you to broadcast that 'test' on 8983... What are you waiting for, John? dxAce Michigan USA Best regards, Jack Painter Virginia Beach, Virginia |
