strength. This can be a useful tool for positioning
the antenna in an optimal location for maximum
signal reception.
4. Turn the Receiver and listen for audio. If no
audio is heard, aim the antenna in different
directions until audio output is heard. This is
the desired antenna aiming position.

position, turn the Receiver off, disconnect the
power adapter from the wall outlet receptacle,
and disconnect the antenna cable.
6. Plan the routing of the antenna cable to the
Receiver. Be sure you avoid any obstructions
that could crimp, kink, or twist the cable. Use
protective grommets wherever rough openings
are encountered.
7.
If the antenna is mounted outside, route the
cable from the antenna position to the interior
