Anyone have any experience designing C-R antennae. I'm building a tri-band dipole for 6m, 2m, 70cm that will be oriented vertically and hung off one of my loop masts on a non-conductive arm. 6m drive
Clay: Unless you're deadset against store bought, check out Comet Antenna's GP-15. It'll cover 6, 2 and 3/4M in one vertical stick. I have one at 80 ft AGL and it works great. 73 de Gene Smar AD

I've looked at the GP-15. Think I'm going to pass. Part of this project is getting experience building a C-R vertical in preparation for using similar designs as the basis for multi-band Yagis. Going
Besides avoiding the inflexibility of the GP-15 design, et al., I am hoping to capitalize on a few features: Balanced design, so if I absolutely wanted to, I could feed it with twinlead, ladder, or o
Rick: I bought my GP-15 in 2001 and installed it at the top of the tower's mast at 80 feet. Before I mounted it I adjusted the length of one of the radials for best SWR at, IIRC, 52.0 MHz. Spec sheet
Several thoughts. First, the fact that it's tuned to 52 MHz with a 2:1 SWR bandwidth of 1 MHz and that it's vertically polarized tells me that it's designed for FM repeater operation. Nothing wrong w
Hey Jim.... Forget the GP-15... That's not why I started this thread... This particular 6m/2m/70cm triband vertical dipole is intended for MOSTLY repeater use on ALL THREE bands here locally.... Sep
Check the cookbook for 6M. You'll probably want multiple chokes in series, 3 turns each on #31 or #43. For 2M, a lot of #31 clamp-ons, for 440, a lot of #61 clamp-ons. 73, Jim _______________________
