[Elecraft] Attic Antenna Tradeoff?

The main thing with an attic antenna is to keep it as far as possible from
house wiring, plumbing, sheet metal, etc.  It wants to be in the clear as
much as possible.

Since house wiring is often covered with attic insulation, you will have to
do a little checking to see where the wires are actually run.  If the
antenna couples too closely into house wiring, and you run 100 watts,
sometimes you can actually see ceiling lights blink, even when turned off.
Happened when my father-in-law visited us.  We hung a dipole across his room
at ceiling height, and boy, did the light blink :-)
That's all "talk power" that is wasted.

Good luck and 73,
Bob N6WG

Subject: [Elecraft] Attic Antenna Tradeoff?

I am currently building a new home and have many challenges regarding the
use of a traditional outside antenna.  I know that an "indoor/attic" antenna
is a compromise, but how much of one??  All things being equal, what amount
of attenuation (receive and transmit)can I realistically expect?  I am just
trying to figure out if I would be happy with an attic antenna for the time
being.  I will use a trap dipole in the attic (about 25-30 feet) with my K2.
Thanks!
