I kept pricing out higher powered 4:1 baluns and found that for what they were, I could buy the parts on line way cheaper than a new one would cost so I bought the toroids and a 5" square plastic electrical box and built one myself.
I already had the wire (14AWG w/teflon insulation), an SO239 connector and some rugged 5 way banana posts.
The first two attempts weren't very pretty but three times is a charm. I learned some tricks along the way and damned if the third one doesn't work very nicely. The article I used said that it would be good up to 2KW...I'll take their word for it.
Cost for a new 2KW Guanella 4:1 current balun was around $90...total cost of parts to build one was $28 plus about two hours of (mostly) fun work.
Yep...I'm cheap.
