For lots (and I mean lots!) of antenna advice, try the avsforum thread here:http://www.avsforum.com/avs-vb/showt...hreadid=381623
The short answer is: higher is better, bigger is better, outside is better,
and directional is better.
If you are getting so many stations already from a cheapo antenna,
you'll be well served by a quality one. The now discontiuned
Zenith Silver Sensor, Radio Shack's double bowtie, Channel Master's
3021, 4228, and the Antenna's Direct DB4 and DB8 are all highly recommended
depending on your distance and application.
Boosting the signal with a Channel Master (CM) 7777 pre-amp is also
helpful if you have a weak (snowy) but not multipathing (ghosting)
I live inside the loop near the museum district and can pick up most
high power stations with one of the crappiest antennas ever made:
the Terk meant for mounting on the back of a DSS dish!
Terk, in general, is junk and this thing is barely better than a couple
of coat hangers since it has so few elements and is really oddly shaped.
So I'm looking forward to getting a Silver Sensor on Wednesday from
ebuyer.com. The Silver Sensors are still widely available mail order
and seem to be a great indoor, non-attic antenna.
Go to antennaweb.com, plug in your street address to get an idea
of your distance and direction from the antenna farm, read that other
AVSforum thread for ideas on antennas and let us know what happens!
