Looks like the gap for lightning bleed-off
should be "just wide enough so it does
not (arc) during transmit". Will be interesting
to see what that distance is, one om said
he thought about 1/16 of an inch. One
good suggestion was to use a "sparkplug"
and I would surely use this had I not already
made the "lightning points" with the aluminimum
yardsticks. Sparkplugs would have been
easy to install as part of the overall feedpoint
layout had I planned for their use. Gee wish
I had asked the question sooner.
Thanks to all who responded.
