The Tactical Radio Gear, (VHF PLUS/Bias-T) combination, is a stand-alone weatherproof system, which permits the insertion & extraction of DC voltage, up to 2.0 amps on coax.

Inserting the control voltage on the coax cable, eliminates the requirement for external wires for powering and controlling remote devices, such as Mast Head preamps, Band Pass filters, remote antenna switching, ET AL.

The design has been optimized to cover 50MHz to 1296MHz frequency range, with the lowest loss and return loss. The Injector incorporates both fuse protection and reverse polarity, to safeguard the system.

The (extractor) is weatherproof; typically, the Bias-T (Injector) unit will reside indoors, for inserting DC on the coax feed-line; while the (Extractor) is placed at the remote device/Mast Head, where the DC voltage is extracted.


Frequency Range: 50 -1296 MHz                

SWR: <1.1:1 across the full frequency range                        

RF Power Handling: >.5KW @144MHz

DC voltage limit: 50 V DC.

DC current capability: 2.5A.   


DC Interface: (Injector) 2.1 mm x 5.5 mm jack         

DC Interface: (Extractor) Waterproof connector, or optional Feed thru Capacitor.                                          

RF Interfaces: ‘N’ connectors (RF, RF+DC)      

Dimensions: H1.0” x W1.0” x L2.0” Length does not include the RF connectors.

A high quality extruded aluminum case with N-type connectors are used in the design for both the Injector and Extractor.  All the necessary cables are included, including the power DC cable

Please select the connector type required for the (Extractor) RF/DC connection.
