Glen, I just build RQ's cylindrical gap set last night. With only 7.5KV -at-
60ma. 450watts I'm getting 18" to 24" air discharges. Tonight I connected a
90cfm blower to the gap to make it quench quicker. I didn't get any larger
sparks, but my relative rf power meter went up from 1.4 to 1.7 and the
sparks to a grounded ball are much more agressive.
Untill you can build a rotary gap, try an air blast gap.
