Gentlemen: I am not one who thinks the whole world revolves around my concerns. And I recognize that some research on my part may be necessary. ( I have read ON4UN's Low-Band Dxing) But I do think th
Hi Dale, I'm no antenna expert, but certainly read as much of the experts publications as I can get my hands on, but having a Teflon brain, it doesn't stick very well. That said, the ARRL Antenna Boo
There is no single spacing for phased elements. There is a continuous variation of both spacing and phasing which has a gazillion outcomes. Two antennas spaced a halfwave apart and fed 180 degrees ou
A wide spaced array offers many benefits when possible. In general the is less coupling between the elements results in better less mutual impedance interdependence. When enough space is available a
Enlightening, but also somewhat misleading... The patterns in the ARRL Antenna Book are correct if the current in both elements is the same. However, if you feed an array of antennas with delay lines
For 2 elements coax phasing is sufficient if 15dB or a bit better F/B is acceptable especially when using low noise receiving antennas. I was more than satisfied with a pair of sloping wires on 160 (
This is quite true although some patterns will be closer to theory than others. In a commercial phasor as is used for broadcast there are several elements that must be taken into account. The first i
