Will I need a pre-amplifier?
If the distance to the transmitting towers are more
than 40 kilometers, you live in difficult terrain, or for attic antenna
installs, a pre-amplifier will enhance your installation.
A pre-amplifier is used to overcome any losses in the coax cable
from the antenna to your TV.
A pre-amplifier consists of two key components:
-
An amplifier, which mounts directly on the antenna mast.
-
A power supply, which mounts nearest to your television set and
plugs into your AC outlet. (should be placed before any splits)
The power supply feeds power back to the amplifier head
via your existing coax cable,
thus
eliminating the need to run a separate power line to your antenna and insuring
that only the television signal is amplified, not any induced noise or
interference that may be present on the coaxial line.
