11.3 Cellular antenna

The selected cellular antenna(s) must meet the following specifications:

 Maximum rated gain of 3dBi for Cellular band and 4dBi for PCS band

 Frequency bands:

 CDMA: Dual-band 800 & 1900 MHz

 EDGE: 850/1900/900/1800 MHz

 HSPA: 850/1900/2100 MHz

 Nominal 50 ohm impedance

 Voltage Standing Wave Ratio (VSWR) less then 2.5:1

 Male SMA connector

The length of the antenna cable may affect the signal strength. Choose the appropriate cable type and length. The table

below provides can help pre-determine the loss to expect.
