60 Hz RF

Half-wave dipole fed by an amplifier?

Best regards, Spehro Pefhany

For the purposes of your statement of requirements, define "good" and "high intensity." An estimate of the target NRE, unit cost, and production quantity/rate would be helpful.

One possible answer for selected values of the above requirements:

1. Stand in your kitchen.
2. Hold out your hand.

Disable the safety interlocks on a microwave oven so you can run it with the door open.

How about a big coil plugged into the wall socket?

We need radiological pollution, more water vapor and louder rap music at traffic intersections much more desperately than we need another 60 Hz EM field.

Use a really big antenna and lots of voltage. Like those submarine comm things.

How about a half-wave dipole fed by the wall plug?

(note the frequency).

(you may need to buy more real estate than is found on your average city lot for the antenna, though).

The transmit antennae for that kind of frequencies are done as a long (~10...100km) cable connected to the ground at the both ends. The effective current return path goes deep under the surface; so the whole structure works like a giant loop.

Dipoles or GPs are getting practical from ~kHz frequencies or higher.

But as far as radiating 60 Hz, just look at the power poles around your house. Get a proper oscilloscope, and touch the probe practically anywhere - we're surrounded by 60 Hz radiation; RF is merely a frequency designation.

Hope This Helps! Rich

Yeah, like from LA to St. Louis. ;-)

Cheers! Rich

But first you'd have to buy uncle Leroy's 2500 acre buffalo ranch :-)

Huh? Try almost a million acres, if you want a proper easement. =:-O

Cheers! Rich

Depends on how high "high intensity" is :-)

Calculate the wavelength, and you'll see why that's a bad idea.

Congratulations, you've just solved one of the most important problems in the history of power electronics. What part of the world are you in?
