ANTENNA CONNECTIONS
Each antenna should be connected to the designated terminals correctly, referring to the following figure.
Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal
strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience
poor reception quality, an outdoor antenna may result in improvement.
Outdoor FM antenna
75-ohm
coaxial cable
Connecting the AM loop antenna
* The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.
* The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.
GND terminal
For maximum safety and minimum interference, connect the
GND terminal to a good earth ground. A good earth ground is
a metal stake driven into moist earth.

FM reception quality, either 300-ohm feeder or coaxial cable
may be used. In locations troubled by electrical
interference, coaxial cable is preferable.
