Beware of running high power, though - the voltage at the top of the tower can
arc over insulated elements, according to anecdotal reports and RF engineer
commentary on Towertalk. I have run 200 watts to a tower with a 40M Force 12
yagi on top for years, but would hesitate, I think, to go much higher.
