I have a 4:1 unun that I made from a balun kit (Amidon I think). It's wound just like a balun, but the connections going out are slightly different. Here's a website:

I get a perfect match on 9 bands,160 - 10. The K3's ATU is magnificent. Your antenna may match, but your radiation pattern will be poor unless you put down radials. See the ARRL Antenna Book for lots of mind-numbing details, or ON4UN's book for even more. Tony KT0NY On Mon, Mar 21, 2011 at 4:11 PM, <[email protected]> wrote: > ...if the K3's atu is sufficient?
