look very suspicious.

You're absolutely right. I don't carry an Uzzi when I do this work,
but I make sure that I have a few business cards and a folder full of
technical papers on transmission line topics. There's also this
little speech that I've rehearsed.... Most important, I have the
names of several people in the power generation and distribution
companies in the area.
I'd say that as long as you don't touch the towers, pointing antennas
at them shouldn't arouse much concern. Just don't look as if you're
up to something bad. It is also a good idea to contact someone at the
power company and talk with them about the problem and what you're
doing. If you do this, you'll have a reference if the police do show
up.
Here in the Austin area, the Lower Colorado River Authority manages
all of the man-made lakes and power generation facilities. They have
an excellent web site (www.lcra.org), and they've assigned an engineer
to handle radio and TV interference problems. You can call him and
get a sympathetic ear. He can't always help, but he'll cover you if
you go out and make some measurements. From talking with him, I have
the impression that this isn't too unusual for power distribution
companies. It's a matter of finding the right person.

Brad, KV5V
