Preparing Your Receiver
For the best radio reception, use an outdoor antenna. Follow these
steps to connect an outdoor FM antenna to the receiver using 75
Ω
coax-
ial cable.
Note: If your antenna has 300
Ω
twin-lead cable, consult your local
RadioShack store for the correct adapter.
1. Disconnect the supplied FM antenna from the receiver’s
FM UNBAL
75
Ω
terminal.
2. With a stripping tool, remove about 1
1
/
2
inches of the outdoor
antenna cable’s outer insulation to expose the cable’s shielding.
3. Fold back the shielding from the inner insulation.
4. Remove about 1 inch of the inner insulation from around the cen-
ter wire.
5. Pull the shielding to one side. Connect the center wire to the
receiver’s
FM UNBAL 75
Ω
terminal. Twist the shielding to secure any
loose wire strands, and connect it to the
FM UNBAL 75
Ω
terminal.
Note: Grounding is not necessary for reception, but we recommend it
for better FM reception and to avoid damage from lightning when you
use an outdoor FM antenna. Use a separate piece of thick polyvinyl
insulated wire to connect the terminal to the building’s power service
grounding electrode system.
Warning: Never connect a wire to a gas pipe for grounding since sparks
might ignite the gas.
Warning:
To prevent injury, read and fol-
low all cautions and warnings that ac-
company the outdoor antenna.
Caution:
The cable’s shielding should
only touch the terminal.
