Hi, i agree with John, as the frequency goes down at some point so does the
charging rate, and so must the total power go down. I have seen power arc's
from a 50 mhz transmitter running 10kw output. It is a wide brush discharge
and short in length. Staying below 1 mhz. is a good recommendation based on
the radio equipment you could cause interference too, like a government
radio system, aircraft, direction equipment, and local public service radio
like fire and ambulance. cul brian f.
