[TowerTalk] Electronic Dog Containment Fence Noisy? NOT

It depends on what frequency it uses. Most of them consist of a wire
buried an inch or 2 below ground, connected to a very low power xmtr on
500 KHz. Usually the dog collars can't pick them up more than a few feet
away. The idea is to run it on power just strong enough for the collar
to pick it up a couple of feet away from the wire. The collar has
electrodes that make contact with the dog's neck and give it a
high-voltage very low current capacitance shock if it gets within the
radio field of the wire.
I have one of these systems myself and have had for probably 15 years at
2 different QTH's. At my current QTH with the fence wire less than 10
feet from the bottom of the crank-up tower and the tower lowered, I can
just barely tell that there's a carrier there on 500 KHz. I've never had
any QRM problems. I don't think you have anything to worry about, at
least not with a properly installed and maintained system operating at
that frequency. If it's a do-it-yourself and/or on a different
frequency, I won't vouch for it.
