Important Information - Please Read Before Installing
Preamplier
1. It is important to install the preamplier as close to the antenna as possible for
best results.
2. This preamplier is not intended for use with antennas that have a built-in
amplier or rotator that is powered over the coaxial cable. (Multiple power
sources on the same coaxial cable will cause issues and potentially damage
your preamplier.)
3. Using high quality RG-6 coaxial cable between the power inserter and the
preamplier is critical. Poor quality coaxial cable or other types of coaxial
cable such as RG-59 and RG-58 can cause intermittent or total power loss to
the amplier limiting its ability to properly function.
Package Contents and Accessories

4. It is important to eliminate all devices in the coaxial cable network that will block
or degrade the power/voltage that travels over the coaxial cable from the
power inserter to the preamplier. Devices that will block or degrade power/
voltage if installed between the power inserter and the preamplier include,
regular non-power passing splitters, other ampliers, satellite splitters and
switches, surge protectors, and lters. If you plan to install a splitter between
the power inserter and the preamplier, it must be a high quality “Power
Passing” splitter. The use of non-power passing splitters and looping coaxial
cable through a surge protector/power strip are the most common causes of
issues.
5. When using good quality RG-6 coaxial cable the maximum distance between the
preamplier and the power inserter should not exceed 300’. (Inadequate or
poor quality coaxial cable will substantially reduce the maximum distance and
in many cases cause complete loss of power to the amplier.)
6. If you have issues with the amplier powering on, you can test the device on
your own to make sure it is functional. Simply remove the amplier from the
installation, then at a table or work bench connect the amplier, power inserter
and power supply using short coaxial cables that are good quality. If the
amplier powers on during this test, this indicates an issue somewhere in the
coaxial cable network. Double check all splitters are good quality and power
passing, make sure all cables and connectors are good quality and remove
other devices that could potentially be blocking power.

Connect the coaxial cable from the AMP output labeled “DC Power IN/OUT” to the
power inserter labeled “TO Amplier”. Next, connect the provided power
supply to the port labeled “Power In” to a power source. Now, connect the port
labeled “TO TV” to the coaxial input on your television or set-top device. Ensure your
television, set-top box or DVR is set to scan Antenna channels, NOT CABLE. In your
device set-up menu, it will typically ask if you want to scan Antenna/Air/Broadcast or
Cable. You will need to choose the option that says Antenna, Air, or Broadcast.
Proceed with the Auto Channel Scan.
