Exactly, Dave! It's right in my Beverage antenna page ("145 ohms"), along
with several different calculators. :-)And all WD-1* wire is *not* the same. Back when I used to sell Beverage transformers, people would send me short samples to measure before I wound them. You have to accurately measure the spacing and wire diameters to determine that, unless you have a long enough piece of it to use an antenna analyzer (preferred). The 6.25:1 is okay for the feed end, but NOT the reflection transformer. I corrected that on the former w0btu.com, but the archived page implies otherwise. 73, Mike W0BTU On Sat, May 9, 2020, 6:52 PM Artek Manuals <manu...@artekmanuals.com> wrote: > More like 150 ohms as I recall > > Dave > NR1DX > > On 5/9/2020 7:34 PM, Mike Waters wrote: > > Fred, those transformers are the wrong impedance ratio for WD1!
