Finished the 1:1 Current Balun

The problem with the balun as I originally constructed seems to be related to contact resistance on the balanced side. I plan to use this on a 1/4 wave vertical so I modified the case to accept a coax connection from the balanced side. It now tests flat SWR across the band. I added a Mega Ohm resistor across the feed point to bleed off any static that may build up on the vertical antenna. Here is what it ended up looking like:

      Yeah building stuff is one thing about this hobby that I really enjoy. Nothing like throwing some wire in the air and talking to someone on the other side of the world!
