A little late comment, but I once had two dipoles on a single coax for 75/80 meters. One cut for mid-phone band, and one for mid-CW band. The two were spread at about a 90 degree angle to each other.

That's a working scheme if you have the space. Probably would work with only a 6 or 8 foot space at the ends too without having to be at right angles. But the smaller fan angle might require a bit of
Novice question: Presumptions: I make a fan dipole. I get the elements and their ends only a foot or so apart from the other elements, respectively. Question: So... Do they couple / interact in a cap

Near the feed point its mostly magnetic coupling, but at the outer ends its mostly capacitive coupling. The fanning idea is more effective the greater the spread out to at least 30 degrees fan angle.
Thanks, Gerry. A local Yocal was trying to convince me it was inductive coupling... and I was thinking capacitive. When you say "magnetic"... I take it that is the same basic concept as when one talk

Inductive coupling IS magnetic coupling. 73, Jerry, K0CQ _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
DOH... Good thing I asked ! [ I TOLD you it was a novice question ! ] Oh well,.... back to the drawing board ( I am reading the ARRL Basic Electronics book and TRYING like heck to remember college ph
