The instructions are at www.w0btu.com/Beverage_antennas.html To test it, put a 450 ohm resistor on the high impedance winding and an antenna analyzer on the low-Z.
And make sure there is infinite resistance between each winding and the core, as 73 material is conductive. 73, Mike www.w0btu.com On Feb 2, 2018 9:59 AM, "MR TREVOR DUNNE" <[email protected]> wrote: Hi I know it's probably been covered here hundreds of times but I'm looking to make a matching Transformer for a 550ft beverage to 75 ohm coax, I have so bn73-202 cores Also how can I test it once it's built _________________ Topband Reflector Archives - http://www.contesting.com/_topband
