Tonight I made a "capacity hat" for my ultra-portable Elecraft AX1 HF #HamRadio antenna.

I found a video by LY2H Linas where he made one based on an alligator clip to make the same antenna resonant on 20m to use with an IC-705. I remembered that I had a box of those clips and got to work.

First I cut off the wire connection from the back (to make it more compact) and filed off the sharp edges.

Then I cut 2 x 245mm pieces of 14AWG solid copper wire, and cut the middle ~15mm of insulation off of each of them. I used a soldering gun to have enough power, and soldered each wire to the back of one side of the remaining clip. Then I bent the wires out into an X.
