Re: Placing CPEs near power lines

If you're back 50-ish feet or so and not looking directly *at* the power lines, you should be OK.

There is also a difference between the high voltage and the secondary distribution voltage. There can be nasty transients on the power lines that radiate quite a distance. If you are near those you might see the effects such as resets, etc.

Good grounding and shielding...

Re: Placing CPEs near power lines

There is a minimum distance you can be legally to any power-line, and I believe that's 15' so do beware for legality and for safety reasons. We have mounted Satellite arms on our own lift poles right next to secondary service (240v) without any problems.

If the wire is covered, it's more than likely =277/480

Anything not covered with insulation is more than likely primary at 7.2kv on up.

If there are bad effects resetting the radios, it is probably magnetically induced common mode voltage. At 150 ft the effect should be negligible. HV lines do not radiate much beyond 50 MHz.
