|Multiple T V Setups...
There are alternatives. One is to run 2 or more antennas. These can be mounted on the
same mast, as long as the antennas are no closer together than they are wide (from side to side).
You do need to run a separate cable from each antenna. We recommend the following setups,
based on "loads". (a TV, Set-top-box, PVR, VCR or FM receiver each count as 1 load.)
At some point, depending on pricing, it is more financially viable to use a multiple port distribution amplifier, generally
after about 4 or more loads, however, sometimes multiple antennas are a better solution than running coax
cable all through a house from a distribution amplifier.
Antenna Amplifiers: An antenna amplifier's main purpose is to boost the older analog signal up compared to
atmospheric noise before being sent down the coax cable into the very electrically noisy house. If you live within
a kilometer or two of the TV site the signal received is probably already a lot higher than the atmospheric noise on the
analog channels. The further from the TV tower, the weaker the signal gets, which means the electrical noise gets
comparatively higher. A digital signal is much more immune to atmospheric noise and as such you can get a lot
further away from the tower before the noise overwhelms the signal. Adding an antenna amplifier amplifies everything
equally, noise and signal, so there is no guarantee that an antenna amplifier will improve an unusable digital signal.
