Impedance: 50
Ω 
 
Centre Frequency: 
833MHz ± 5MHz  (for 800MHz modem) 
 
921MHz ± 3MHz  (for 900MHz modem) 
 
Frequencies of operation: 
806 to 825MHz (for 800MHz transmit) 
  
851 to 870MHz (for 800MHz receive) 
 
896 to 902MHz (for 900MHz transmit) 
  
935 to 941MHz (for 900MHz receive) 
 
Acceptable return loss: 
VSWR < 1.5 or RL < -14dB (recommended) 
  
VSWR < 2.0 or RL < -10dB (minimum) 
 
The power output of the Boomer II OEM Modem is nominally 1.8W at 
the antenna port. The antenna gain or loss will affect this value. 
For reference Wavenet used the following ¼ wave whip antennae for 
FCC certification and these are included in the Integrator Developer 
Kits; 
 
800 MHz modem: Radiall/Larsen - SPWH20832 (blue tip) 
 
900 MHz modem: Radiall/Larsen - SPWH20918 (red tip)
