question QTH ? What is your location !!
If your are more than 15 miles or less than 100 miles from your TV
transmitter a good antenna system is required, At these distances you must
point your antenna with an accuracy of +/- 5 degrees to get a good signal.
An Omnidirectional antenna works well up to about 10 miles but then so would
a coathanger . I would have to assume that you are outside or beyond a cable
TV, COGECO ? service area else why would you want to put up an expensive
$200 antenna to get one station when you can get a satellite setup for ~
$100.00. If you live in a Metropolitan Area., I can understand trying to
avoid cable fees. Your question about amplifiers fails to recognize
something called Signal to Noise Ratio a weak signal usually implies low
SNR, further amplification will bring in a stronger signal but also much
more NOISE or snow. A better antenna will improve SNR ie. a stronger signal
with the same amout of noise, noise being background atmospheric static
which is always present in any signal. I would have to assume that you must
be using a dial-up MODEM because this question doesn't make much sense if
you are using a Cable MODEM and already have access to a Cable Service

. They
could not explain it to me at the store.

Second question is about buying one of those omnidirectional TV antennas
that look like a flying saucer. I believe they have a built in
amplifier. If I bought one should I use it in combination with my old
indoor amplifier? Thanks a lot for your help.
