Telular SX4D user manual Antenna Setup, Optional Yagi

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:

Optional Yagi

•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.
