Antenna Power Supply LTC LXG04PK with F-type Socket, 12V

The LTC LXG04PK antenna power supply provides a steady 12V DC feed for active antennas and inline amplifiers via an F-type socket. Designed to inject power over coaxial cable, this unit enables signal amplification at the antenna, improving reception for terrestrial TV, FM and other RF installations that require a 12V supply. The compact design fits into typical antenna setups and is intended for use where powering an active antenna or inline amplifier from a central receiver or power inserter is needed.

Advantages

This power supply delivers a regulated 12V output through an F-type connector, enabling simple and reliable DC-over-coax power delivery. Its design supports installation with standard coaxial cables and common RF equipment, reducing the need for separate power lines to the antenna. The unit is suitable for continuous operation and helps minimize signal loss by placing amplification as close to the antenna as possible.

Suitable for

• Feeding active rooftop or indoor antennas that require 12V DC
• Powering inline amplifiers placed near the antenna to boost terrestrial TV signals
• FM antenna installations where remote powering via coax is preferred
• Situations where DC power must be injected into a coax run to remote RF equipment

Key specifications

• Output voltage: 12V DC
• Connector type: F-type socket for coaxial connection
• Power delivery method: DC-over-coax (power injected onto the coaxial cable)
• Designed application: Active antennas and inline RF amplifiers for terrestrial TV, FM and similar signals
• Form factor: Compact housing suitable for inline installation in antenna systems

How to use

Connect the F-type socket of the power supply into the coaxial feed line between your receiver or distribution system and the antenna or inline amplifier, ensuring proper F-type thread engagement. Confirm that the connected antenna or amplifier is rated for a 12V supply before powering the unit. After secure connections, apply mains power to the supply so it can inject 12V DC onto the coax; verify operation by checking signal quality at the receiver and ensuring the amplifier or active antenna powers up as specified by its manufacturer.

Usage recommendations

Use high-quality, properly shielded coaxial cable and correctly tightened F-type connectors to minimize signal loss and prevent intermittent power connections. Avoid routing coax near strong sources of electrical interference. Verify polarity and voltage requirements of the connected antenna or amplifier to prevent damage. If the installation requires weather exposure, ensure connectors and the unit are protected against moisture with appropriate sealing or enclosures.
