AM Antenna
Connect the included loop antenna for AM recep-
tion to the back panel, attaching the GND
(ground) and AM ends to the appropriate con-
nections for each tuner.
FM Antenna
Attach the included FM antenna to the FM COAX
connection on the back panel by pushing the
F-type quick-connect termination of the antenna
onto the FM connection.
External Antenna
It is recommended to use an external outdoor or
attic-mounted long wire antenna for best per-
formance for AM/FM reception. For AM, use a
75-ohm to 300-ohm balun at the AM connection
on the tuner, and attach the 75-ohm coax cable
to the balun. For FM, attach the desired length
of 75-ohm coax cable directly to the FM connec-
tion on the tuner.
