Hi Ed...

The resistors need to be carbon composition and at least a couple megohms each. IIRC mine are around 3 meg per leg (not sure....maybe their value shows up in the attached photos), maybe 1/2 watt resistors?. I ran each leg of the feedline to ground via a 1+ meg resistor (nothing across the ladderline). This will be hi-Z for RF and will be invisible to your antenna network, but if there is static DC voltage on the antenna or feedline, it'll bleed it to ground. Values are probably not critical (higher wattage & resistance is better), you just want to have something of high resistance to bleed off charge. If the antenna gets hit by lighting, everything is vaporized and hopefully the spark plug gaps and bleeders will spare your equipment. Or not.

Attached photos tell the story better than I can. If you need more info, let me know!

Good Morning Dan:
Re your comment on static bleeder resistors and ladder line, could you clarify if you connect the resistors across the ladder line (wire to wire ) or you are connecting each of the wires in the ladder line to ground through the resistor?

Also, do you have a suggestion on adequate power rating of the resistors?


Thanks,
