ST2S SETUP AND CONNECTIONS
ANTENNA CONNECTIONS 
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 Tuner 2. 
It is recommended to use an external outdoor or
attic-mounted long wire antenna for best per-
formance for AM reception. 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.
FM Antenna
Attach the included FM antenna to the Tuner 2
FM COAX connection on the back panel by push-
ing the F-type quick-connect termination of the
antenna onto the FM connection.  
It is recommended to use an external outdoor or
attic-mounted long wire antenna for best per-
formance for FM reception. Attach the desired
length of 75-ohm coax cable directly to the FM
connection on the tuner.
