I was wondering if anyone knew how to make a balun for the Antennacraft St-2 Its seems to me the transformer that comes with it is junk. The threads where the coax connects seems to be loose on mine. Sloid Signal wants me to send the whole antenna back but don't have the box and it would be a pain for me to ship it back. I was thinking of makeing a balun out of coax but not sure how many turns in the coax and what size should the coils be. Any Help?
