Gary, was your 140 ohm WD-1A made from .0393 (1mm) diameter wires, spaced .118 center-to-center? My math says that should be a little over 140 ohms.
But the stuff I was talking about was a different diameter and spacing (.033 diameter and .0685 center-to-center spacing.) The same math says it's ~115 ohms, but I had no way of measuring a piece less than a foot long. 73, Mike www.w0btu.com On Mon, Jul 23, 2012 at 1:49 PM, kd9sv <[email protected]> wrote: > Mike, the measurements I took here on a short (300ft) WD-1A with average > height of 5ft using the method W8JI recommends with a termination resistor > (pot) and MFJ-259 showed an impedance of 140 ohms on both 160 and 80 > meters. > I did not attempt to measure at higher freq's...de gary, kd9sv > _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
