Understanding, Building, and Using Baluns and Ununs
A couple of weeks ago, I had a post about needing to build a balun to use with my loop. I am trying to do more remote operation, and obviously with a manual tuner it makes it difficult. The manual tuner has a built in balun that allows me to use my loop with dual rg-6 coax.
I did a little research and found that many ham’s reccomended Understanding, Building, and Using Baluns and Ununs by Jerry Sevick, W2FMI. I went on Ebay and found a copy for 49.00 and purchased it using Buy Now. Well long story short, I never did receive the copy and after about 3 or 4 weeks Ebay refunded my money since the seller wouldn’t respond to my or their messages.
So I went back on Ebay and no copies were listed this time. I checked Amazon and several people had copies, but most started at $150.00 or more. So I went back and checked. It was originally available from CQ magazine. I went to their website and lo and behold, they just got in a new printing of the book. So for $19.95 plus shipping you can purchase a brand new copy of it here.
I have my reading set out for me the next couple of nights. I will let you know what I learn and more importantly what I build.
Thanks for the heads-up on “Understanding, Building and using Baluns and Ununs”. I’m in the UK and amazon.co.uk sellers were quoting 127GBP for a used copy. I order my new copy from CQ mag and that’s cost me under 45GBP with shipping.

Universal Radio carries the latest edition of that book.
You are going to enjoy reading it. It is packed with a lot of very good
information. When you are finished reading that book, search, “K9YC” and
sift through his material. I think the article you need to read there is
about RFI in the audio. One of his articles really focuses on chokes and
baluns. You’ll learn there that #31 material is one of the best choices to
use in baluns and chokes. But you won’t go wrong by using #43 material.
Good luck with your projects.
