Hitachi FT-4000 - Alignment Procedures

Outdoor AM Antenna
When using this set far from the broadcasting
station or at a place where the radio reception is
adversely affected by ferroconcrete buildings or
some other structure, install an outdoor antenna.
Connect vinyl wire to the AM ANTENNA ter-
minal @2 on the rear of this set, and install the
antenna a short distance from the building. Fix
the antenna where the best radio reception can
be obtained.
