9  PREPARING FOR OPERATION 

 
 

EQUIPMENT PREPARATION 

 
Before leaving the equipment base to undertake an operation it is recommended that the 
following equipment checks be made. 
 

9.1  The RFX-RMT-II Transmitter 

 

9.1.1  Antennas 

 
Depending  on  the  frequency  band,  the 

RMT-II  can  be  used  with  a  variety  of  RF  Central 

antennas 
 

  CO  series  Omni  antennas  are  typically  used  for  ground  based  mobile  operations,  or 

helicopter air to ground 

  GPS controlled antenna for helicopter air to ground 

  PA series low profile antennas are used for uplinking ground to air, or on-board linking 

  HX series antennas offer increased gain and directivity 

  FBA fan-beam antennas offer increased gain and 90 degree sector coverage. 

  Parabolic antennas offer the highest gain, and longest operation range 

 

9.1.2  Checks 

 
Confirm the correct encoder mode of operation is selected. 8.4.6 
 
Confirm the correct frequency is selected. 8.4.1 
 
Confirm the correct Video input type is selected. 8.4.3 
 
Confirm the correct Audio input type is selected. 
 
Confirm the correct Audio level is selected (analog audio only). 8.4.2  
 
Check that the Video, audio, DC and RF cables are in good condition.
