Default Anyone recommend a source of 36:50 ohm ununs?

Hi. Can anyone recommend a source of 36:50 ohm ununs?

I'm adding an inverted L for 160 meters and would like to add an unun of 36
ohm to 50 ohms to reduce my SWR. EZNEC shows it would lower it
substantially and when you're running barefoot on 160 you need all the help
you can get.

Thanks, Bob VE7HS


I don't have a source, but I have Jerry Sevick's book,
"Transmission Line Transformers"fourth edition.
On pages 7-4 thru 7-15 are descriptions of how to wind
32 ohm to 50 ohm UNUNs.
I found this,
http://documents.mx/documents/amidon...shandbook.html
Go to page 39 of the book (pg 61 of the docslide) and see the 5 winding
configuration to give you 32 ohm to 50 ohm.


If you search W2FMI-2:1-HU50 using Google it is the first hit
and show several approaches. I think this is the same as above.
