Re: Indoor Antennas



Hi Stan:

I have never tried an attic antenna for any band higher than 432.  However,
I would expect that the roofing nails would cause severe attenuation,
especially at 2.3 GHz. and above.

The shingles could also cause additional attenuation.  Try putting the same
type of shingle that you have on your roof, in your microwave oven for
several seconds at half power.  If it does not get warm, increase the power
to high and check it again. If it still does not get warm, try it for 30
seconds or so and see if it gets warm.

Microwave ovens operate very near our 2.3 GHz. band. If the shingle does not
heat up, you will know that the only attenuation you have to worry about is
from the roofing nails.

Good luck & 73,
