Hello Fred, Absolutely you can! Earl, K6SE (SK) swore by it. I have two bi-directional Beverages made from that stuff, which are described in detail at http://www.w0btu.com/Beverage_antennas.html. 73

Fred, I just put up a 600 ft beverage with 17 ga. fence wire after reading those reflector posts about beverages last month.  It cost me less than $10 for the wire, and I am absolutely amazed by the

You weren't kidding! I've used the Beverage mainly for listening on 160 and below, but on 40 meters, WOW! Thanks for lighting a fire under me. I just built a 40 meter ground plane I designed in EZNEC

What may be more destructive is a slow velocity factor in the insulated wire. There is no way to estimate that, you just have to measure it. If the VF is low, then you get into the same kind of probl

I'm just thinking about the probably slow velocity factor of the stuff Jacques describes, the loss, and the poor performance it would give if used for a reversible beverage. The losses as a reversibl

Hi Guy, Good topic. Slow wave structures are more common in microwave. Anything that increases capacitance or inductance per unit foot will slow wave propagation. The formulas are 1/f*sqrt LC for wav
