Antenna Question
 

I have a dipole in the attic tuned to around 14Mhz. Whenever I
transmit at full power, the laptop sitting next to my rig goes crazy
and the light in the next room turns on (its hooked up to a clapper).
When on 80 meters, if I transmit at full power and use my antenna
tuner to tune near perfect SWR, the treadmill in back of me turns on.
Is this normal? Should I worry about excessive radiation?

Thanks,
Dan

Radiation?? What radiation??

You need to figure out how to solve the paranormal activity thats taking
place

Is this normal? Yep!

Should I worry about excessive radiation? Nope!

You have RF coupled into the power lines. You need some type 43 clamp on
ferrites to solve the 'normal' RF susceptibility of those components.

Dan, you're (relatively) safe, but your household electronics may be in
danger G...

You might want to look at RF grounding, or try changing the lengths of your
dipole or the feedline (assuming it is coax?) . You might not fix all your
problems, but you can alleviate a lot of them. The rest comes down to
quality of design of the devices you're turning on...

Yes, you are probably getting RF'ed to death. I would try to use the
lowest power necessary to carry on a QSO if you are using an indoor
antenna. This is a common occurance with modern equipment with
electronics in it. You might want to get the RF Exposure book from ARRL
to assess your exposure to RF fields.

Thanks everyone for all the responses. Would using a surge protector
on the devices being RF'd to death help?

Thanks,

Some of the surge protectors have RF isolation, but most of the
low-cost ones do not. Winding the cords around a ferrite rod might
help, but I'd try connecting your antenna tuner to a good ground, then
follow the advice of someone else here - use only enough power to
maintain communications. Balanced feeder to the antenna line will
probably help also if that's possible in your situation.

Sounds normal to me VK3DTO
