The (Extractor) unit must be protected against weather. Wrapped in plastic saran wrap, plastic bag
and/or sprayed with a protective clear enamel/lacquer coating. Many excellent weather proofing products are available to protect the unit.
The (Extractor) coax connections will need protective measures: DXE-33PLUS - Scotch® Super 33+.
Highly conformable super stretchy tape for all weather applications.
Thank you for your purchase of the Tactical Radio Gear, (Bias-T). This exceptional 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)
Inserting a control voltage on the coax cable, eliminates the requirement 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
The Bias-T (Injector) unit resides indoors, for inserting the DC voltage on the coax feed-line; while the
(Extractor) is located at the remote device/Mast Head, etc. Where the DC voltage is extracted.
Frequency Range: 1.8 MHz – 54MHz
SWR: <1.01:1 across the full frequency range
RF Power Handling: >1KW @ 30MHz
DC voltage limit: 36 V DC.
DC current capability: 1.5A.
DC Interface: (Injector) 2.1 mm x 5.5 mm jack
