<< Several years ago, there was an article in one of the ham magazines that
described the use of static wick dischargers to reduce p-static noise.
These wicks were, as I recall, about 6" long and were mounted either on
the ends of the boom or near the ends of the elements. I don't remember
what the material was, but it wasn't metal and was a high resistance
conductor. Noise reduction in the 20-30 dB range was claimed. Has
anyone had experience with these devices. And, if they work, does
anyone know where they can be found? >>
Yes, these devices are used occassionally for commercial tower
applications. The theory is that they dissipate the static build-up before
it gets big enough to attract a lightning leader. Some users in lightning
prone areas such as Florida swear by them.
TOWER TECH handles the Tower*Guard, a 24 inch diameter ball that is
mounted at the top of the tower. The tower has to be connected to a good
ground system or else the static charge doesn't have anywhere in which to
bleed. They are $99.50 and are made out of stainless steel for long service
life.
