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 Book has a page that shows the patterns of various spacings and phasings of vertical antennas, which I found very enlightening. 73, Gerry, K8GT ---- Dale Long <[email protected]> wrote: ============= 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 this is a reasonable question, and think that there are knowledgeable folks who might provide some advice. Unfortunately I have never done any antenna modeling. Please let me know your thoughts.

Ok, I am willing to accept that. My question is if you have verticals that are 1/2 wave apart, would it not give some pattern, whatever that should be? If you were looking for an endfire pattern how should you feed such verticals? If you have specific questions, you may contact me directly at [email protected] Thanks and 73, Dale N3BNA _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
