Al, It is somewhat unconventional to all of us used to single wire antennas. That is why it works better than the Isotron, the EH, or the other small antenna ideas that do not contain full resonant l
Antennas radiation is directly tied to ampere-feet of linear distance, nothing else. EM radiation occurs because of charge acceleration, nothing else. 200 feet of wire in a ten-foot physical length
Well, I do not disagree that capture area is all important to great antennas. But for the condo owner with antenna restrictions, he is never going to see the antenna farms that Tom and I love to buil
Hi Stuart, Capture area or effective aperture is not directly related to physical size, even though that is a popular misconception used to tout physically large antennas. Capture area relates direct
Hi Tom, I NEVER claimed the folded conical Helix was better than all other antennas, I said it was more efficient than some small antennas of comparable volume which it is. The Isotron and most other

Hi Stuart, First you said the cone antenna was 90% efficient and the MFJ loop was 10% efficient on ten meters. Now you say "**some loops** are 10% efficient". Of course that is correct, because some
