What is "a lot taller"? I can't answer that question specifically. It varies with e-field conditions and the type of antennas and structures. The corona is a micro power noise generator so it radiates noise, and the target has to neutralize the field near other points so they don't break i

Tom, What is "a lot taller"? Would an aluminum or steel (or combination) mast extension with pointed tip, extending say 10-20 feet above the top beam -- let's say one for 20m -- help to reduce corona discharge noise in the top beam? 73/Jon AA1K On 11/16/2012 6:58 PM, Tom W8JI wrote: Hi woul

Hi would a static discharge wick mounted on the lightning rod be helpful? They seem to work well for aircraft AM radios. << Anything a lot taller than the antenna being used and close to the antenna can help reduce corona from the antenna itself, because it is a better "leak point". This is wh
