10 to 13 element beam

I run a 13b2 at 60 ft.. works better than I thought it would. It's fed with 300 watts (if needed) and 1/2 inch hardline. My buddy south of me has run a 17b2 at 125 ft for several years without a problem. With 100 watts he kicks some ass at that height.

I have a bunch of antenna and tower work to do next year. Part of that is installing a pair of 13B2's at about 70 feet.

Compensating for something else. Don't these idiots know massive amounts of rf can affect certain regions of the human body?

At 2.4 GHz, yes. It's called a microwave oven. Not good for you.

At 27 MHz, it's for "medicinal purposes". Perhaps someone can use that excuse when the FCC comes knocking?

Short wave diathermy operations use the ISM band frequencies of 13.56, 27.12, and 40.68 megahertz. Most commercial machines operate at a frequency of 27.12 MHz, a wavelength of approximately 11 meters.

There is one of those medical diathermy operations in a town about 11 miles from me. It wipes out Channels 12 13 14 and 15 here with about 5 s units of weird pulsing sounds. For some reason it goes on 24 hours a day.
