- Jerry, I apologise - I misunderstood which set of dimensions you had a problem with. For what it's worth, the N6LF QEX dimensions model OK, John's 80m dimensions model OK, but I can't get close with

- Hi all, Shortly before we lost him all too early, I sent L.B. Cebik a note describing an idea I had for a vertical dipole. While he didn't go in to great detail, he did offer an excellent suggestion:

- Kelly, let me make a suggestion here... For feeding this shortened vertical (OCF) at the junction of the hat and the vertical wire I would suggest a link coupled arrangement... Even though the feed p

- This is not meant to suggest that it is not a compromise antenna, but I use the Hy-Gain AV640, which is a 3/8 wave radiator (either full (electrical) size, or shortened by a capacity hat, or one coil

- I can see what Jerry K4SAV is talking about. Using a 45 foot vertical wire and four 65 foot hat wires indicated by EI7BA, resonance is around 2.36 MHz in my EZNEC model. This varies somewhat dependin

- Hi, Anyone have any information on how vertical dipoles perform when elevated? If I had one, I'd want to get it off the ground and above foliage, but I've only ever seen photos of them on the ground.

- K9YC has vertical dipoles in tall trees similar to what you describe. You can see information and pictures in his PPT starting at about figure 60. http://audiosystemsgroup.com/NCDXACoaxChokesPPT.pdf
