  LF-HF-VHF-UHF Dual Port By-Pass relays. How it works.  
     

 

 

Default state. (By-passed)

When the Dual Port By-Pass Relay is not activated, pins 3 and 4 of the control line connector are open or the unit is not powered the device plugged on Port B and Port C is by-passed. Both ports (B and C) are grounded.

Port A and Port R are connected.

 

 

 

 

 


Active state. (NO By-passed)

When the Dual Port By-Pass Relay is powered and pins 3 and 4 of the control line connector are joined the internal relays switch-over. The device Input (Port B) is connected to Antenna (Port A) and the Device Output (Port C) is connected to the Radio (Port R).
