Capacitors for use to block DC in SSB
Digi-Key, (800) 344 4539.
Type X7R Monolithic Ceramic capacitor, 0.15uF, $0.91 each,

"... Fasten the RF ground tape securely to an insulating piece of phenolic or to a terminal strip, cut a 1/10-inch gap across the tape, and solder several 0.15uF ceramic capacitors across the gap. These capacitors will be transparent to the RF, which will be happily grounded by the ground tape system, but they will block any DC currents from running through the RF ground system, and will avoid any resulting susceptibility to hot marina electrolytic corrosion..."
