Kenny,
I used three large torroid cores, 12AWG silver/teflon wire, and 10
turns/14 turns to match 25 ohms to 50 ohms. There is a picture of the
transformer in my Phasing Switch Box at:

To give you some perspective of size, it is in a 8" x 8" box.

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.
