Step 1. Antenna Setup
The Phonecell SX4D comes with an antenna. However, your coverage area may
require a higher-gain antenna for optimal call clarity and performance. The Phonecell
SX4D is compatible with a variety of antenna options, including magnetic-mount and
Yagi models – not supplied.
Your Phonecell 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 optimal call clarity. After you choose a good location,
connect the antenna, test the signal strength and adjust the location accordingly.
Antenna Setup:
Connect the antenna to the TNC
antenna connector on the rear panel of
the Phonecell SX4D - see Figure 1.
Antenna Tips:
••
Locate the antenna above ground
and as close to windows (or exterior
walls) as possible - see Figure 2.
••
Standard, magnetic-mount and
elevated feed antennas must
always point directly upward.
••
Yagi antennas must be directed
toward the service provider’s near-
est cellular tower.
••
Keep antenna cable as short as
possible – long cables may reduce
call quality.
••
Never splice antenna cable.
