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

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
