@) @) FM/AM ANTENNA TERMINALS
Both FM and AM antennas can be connected to the tuner’s
terminals. One of the terminals is used to connect an FM
antenna to the tuner in the manner shown in Figure 2. Other
terminals, the AM antenna terminal and GND terminal are
used to connect the high-performance, low-impedance, AM
loop antenna that is provided with the tuner. See Figure 2.
The AM loop antenna can be used on top of the tuner or can
be mounted on a suitable rack or shelf near the tuner.
Interference may be reduced if the tuner is earthed as shown
in Figure 2.
