HOMEBREW 4 TO 1 BALUN

Postby ku4gw » Wed Jan 27, 2010 1:49 pm

Found the plans for this 4 to1 balun and made one for my 260 feet doublet and it works like a charm! Here's the link if you want to make one of your own. If you need further instruction on where exactly to solder the ladder line and coax drop me an email and I'll send you the instructions for that. Here is the link: http://www.bloomington.in.us/~wh2t/balun.html Materials needed consist of a 6 inch piece of around 1 inch diameter PVC pipe and enough of Romex house wire for 12 bifilar turns. He says that if you use 10 gauge solid copper it will handle legal limit just fine. I used 12 gauge solid copper and it handles a kilowatt OK. This little project save me $82.00+shipping for a manufactured balun at http://www.balundesigns.com/servlet/the-69/4-cln-1-balun/Detail.

COAX AND LADDER LINE CONNECTIONS INFO

You solder one end of the ladder line to the white wire at the top of the balun and nothing else solders to that point. You solder the other end of the ladder line to the black wire along with the coax center conductor on the opposite end of the balun. The coax shield only solders to the middle of the balun where the white and black wire solder to one another. I can email you a labeled photo if you will drop me an email to my email address listed at my QRZ.com profile at http://www.qrz.com/db/KU4GW
I think that the Dr. Ace's website I previously listed is permanently down because I've tried to load the page unsuccessfully on several occasions.
