KM,

What you say/wrote about electical wiring in the Attic is very true.
- - - Especially if you have any major electrical equipment mounted in
the Attic or on the Roof. Air Conditioners, Fans, ETC.

For Attic Electrical Wiring and Noise
(When the only place you can put an Antenna is in the Attic.)
- - - Think Horizontal Loop Antenna

IMHO: The best type of 'antenna' to use in the Attic is a Horizontal
Loop Antenna. Loops generally have lower/less man made noise pick-up.

* Mount it at least 3-6 Feet above the Attic Floor and follow the
Primeter of the Roof.
NOTE: This has to be a compromise Height vice Size.

* Use a Matching Transformer in the Attic and a Coax FeedLine from the
Attic down to the Radio. (More Noise Reduction.)

Tim,

One thing you will want to check before running your antenna wire on the roof
is the possibility of any electrical service wiring running in the attic. It
may be that if you have AC wiring in close proximity to the antenna, especially
running parallel to it, you could pick up some line noise on your antenna feed.
