Topband: 1:2 UNUN

[Frank W3LPL]

Hi Kenny,

A very workable alternative is to use two lengths of 75 ohm coax
in parallel.  RG-11 is the best choice, but two lengths of RG-6
will also work. No need to coil it up, simply use it as part
of your transmission line from your antenna base to your station.

Does anyone have a drawing on how to wind a 1500w 1:2 UNUN?  And what type of core is needed?

This is for my 160m vertical which is about 28 ohms.
