Converted Frequency Formula

Use the following formula to calculate the converted frequency:    

      TX: 

ƒ

RF OUT

 (GHz) = 

ƒ

IF IN

 (GHz) + 27.35

    

  

      RX: 

ƒ

IF OUT

 (GHz) = 

ƒ

RF IN

 (GHz) -  27.35    

Note: Electrostatic deposition powder coat, scratch free.

Note: Vent holes are covered with a Goretex

TM

 patch.

Note: The transceiver mounts to a vertical pole of 2.5” to 4.5” outside diame-
ter. It has a range of motion of 90

°

 

over and -60° under horizon. The bases of 

the antenna mount can rotate 

±

180

°.
