BIAS-T
The Tactical Radio Gear, (Bias-T) combination, permits the insertion and extraction of DC voltage, up to 1.5A @ 36v amps on coax.
Note: Higher current and frequency ratings are available. (See CONTRACT WORK)
APPLICATIONS
Inserting a control voltage on the coax cable, eliminates the necessity for external wires, necessary
for powering and controlling remote devices, such as Mast Head pre-amps, Band Pass filters, remote
antenna switching, ET AL.
The design has been optimized to cover 1.8MHz to 54MHz frequency range, with the lowest possible
loss. The Injector incorporates an internal fuse, and reverse polarity protection, to safeguard the
system. Note: Higher frequency ratings are available. (See CONTRACT WORK).
INSTALLATION
The Bias-T (Injector) unit resides indoors, for inserting the DC voltage on the coax feed-line; while the (Extractor) is placed at the remote device/Mast Head, etc; Where the DC voltage is extracted.
