I would just add a couple of things to the excellent write up that Stephen
did.  If the problem is too much signal, you can get attenuators that you
put inline with the antenna feed. If the problem is not enough signal, an
antenna outside high up is better than one in the room with the TV.  If the
antenna is a long way from the tuners, an amplifier near the antenna is
what you want.  They can be powered through the coax so the power can be
near the TV and the amplifier can be mounted on the antenna pole. Note that
there is loss in the cable which is why you want the amplifier near the
antenna.  There are also different grades of cable and the cheaper ones are
not very good and can "leak" signal and pick up interference. This is more
important if you don't have an antenna but get tv through a cable
provider.  The leaking cable can pick up OTA signals and really mess up the
ones in the cable as they are at the same frequency. You might even pick up
enough of your station that it cancels out the main signal but that is not
very likely.  Best cable is Quad shielded and pretty stiff. Connectors are
important as well and the best ones are pressed on with mildly expensive
tools although the cheaper ones might work as long as they stay out of the
weather. I am not sure if anybody uses "twin lead" any more but that is
fine as long as it doesn't run over any metal. It doesn't last as long
though and I think is pretty much out of favor.
