This may sound crazy, but I've used a piece of double sided circuit board at up
to 1KW to feed an 80M vertical. Cut it to size, and campher the edges back
1/8" or so. Then wrap the edges with electrical tape. Solder a wire to both
sides, bodda-bing-bodda-boom a capacitor. Camphering the edges is believed to
increase the voltage handling capability of the board. It also changes the
capacitance dramatically (downward) so you need to campher before measuring.
