Optimus STA-795 - External FM Antenna

External FM Antenna
For improved FM reception, you can use one of
the following:
• TV rabbit ears (for indoor use only)
• Outdoor VHF TV antenna
• Separate outdoor FM antenna
Before you connect an external FM antenna,
disconnect the FM line-cord antenna from the
receiver’s 300 Q terminal.
For best reception from an outdoor antenna, use
75-ohm coaxial cable as antenna wire.
Using Your TV Antenna: If you plan to use
your TV’s outdoor antenna, you need a
VHF/UHF/FM signal splitter, such as Radio
Shack Cat. No. 15-1252.
Connect the TV’s antenna wire to the splitter’s
inputs. Connect the splitter’s output(s) to your
TV’s antenna terminal(s). Then, use 300-ohm
twin-lead to connect the splitter to the receiver’s
300 Q terminals.
Using an Outdoor FM Antenna: if the antenna
wire is 75-ohm coaxial cable, follow these steps
to connect it to the receiver.
1. U se a wire stripper to remove about 1 inch of
the cable's outer insulation. This exposes the
cable’s shielding. Then, fold back the shield¬
ing over the outer insulation.
2. U se a wire stripper to remove about 3 A inch
of the inner insulation. This exposes the cen¬
ter wire.
3. C onnect the center wire to the receiver’s 75 a
terminal.
4. S ecure the shielding with the GND terminal’s
metal clamp.
Caution: Be sure the shielding touches only
the GND terminal.
