Step 1. Choose an Antenna Location
Your Phonecell SX3 receives operating commands from the
cellular network and relies upon signal strength for proper
operation. Therefore, finding an antenna location with good
signal strength is critical for call quality.

:
••
Locate the antenna above ground and as close
to windows (or exterior walls) as possible – see
Fig. 1.
••
Try to install the antenna in an uninhabited area
(i.e. closets, attics, etc.) to ensure a minimum
separation of 16 inches (40 cm) between the
antenna and the inhabitants.
••
Preferably, the antenna should be mounted on
the building’s exterior – see Fig. 2.
••
High-gain (“Yagi”) antennas must be directed
toward your service provider’s nearest cell
tower.
••
Spike antennas must be pointed upward.
••
Keep antenna cable as short as possible – long
cable runs affect call quality.
••
Never splice antenna cable.
