RF SAFETY

Post by N9LCD »

I'd like to start HF operations but I can't put-up an outdoor antenna for site specific reasons.

I'm thinking of running a maximum of 150 HF watts into an indoor antenna. I'd be in the same room with the antenna.

Would I be exposed to unsafe levels of RF? What about other areas of the house, especially those above the antenna?

Thanks & 73!

Lots of options here;

Run a long wire down side of building to flag pole

run a long wire, under eave of house, all the way around the building

if using a shingle roof, run ant wire around in the attic


all the above requires an external tuner, a decent wide-range matching type.
Heck, anything up can be tuned and used, and a good ground is critical. a cold water pipe is good if it goes directly to ground. NEVER use a stove line or gas line, for obvious reasons.

There are several online programs to calulate rf exposure..

I dnot thein 150 watts in the same room will pass muster..

my 100 wats to G5RV 24 feet abover the house is borderline.

TH6 70 feet from house and 43 feet up is no sweat to any power...


run the calc program and be sure.
