I am looking for plans for a transformer/balun to couple 50 ohm at 50Mhz to
300 ohm. The purpose is to load a TV antenna, allowable by HOA, on 6M. I
have tested this antenna, using the standard transformer from 300 ohm to 75
ohm, using a MFJ SWR meter/analyzer and the SWR is flat from 50Mhz to
440Mhz. Obviously there are a couple of peaks and dips. But it has decent
SWR in the ham bands. It even has a F/B of approximately 15-20db based on
S-meter. Looking to run approximately 100 watts.
I have looked on the web via google and have had no luck - either I am using
the wrong search criteria or something else.
Thanks for your help - I am trying to help a ham get on the air who got into
the hobby after he bought a house in a HOA development.
