[BC] More thoughts about AM transmitter lightning

[nakayle at gmail.com]

 It seems to me there is a great market for  "vacuum ball gaps"- made
similar to vacuum variable capacitors.  The problem with conventional ball
gaps is that they are exposed to all sorts of varying conditions- rain,
dirt, insects, paint, etc so they must be set wide enough for the RF not arc
with even in the most adverse weather like heavy rain.  If the balls were
enclosed in a sealed vacuum container they would be in a stable dry
environment and could always operated at the optimum spacing.
