Antenna Power Supply LIBOX LBZ-3/L/01 with F-connector

The LIBOX LBZ-3/L/01 antenna power supply with an F-connector supplies DC power over coaxial cable to active TV or radio antennas and inline signal installations while allowing the RF signal to pass through. Designed for domestic and small-installation use, this in-line unit feeds masthead amplifiers or preamplifiers without interrupting the antenna signal path. The compact design integrates with existing coax cabling and F-type connections, providing a simple solution for remote antenna powering needs.

Advantages

The device delivers stable DC power to masthead amplifiers via the coaxial cable while preserving the RF signal, reducing the need for separate power lines. Its F-connector compatibility ensures straightforward connection to common TV and radio installations. The compact inline format is suitable for mounting in equipment racks or near terminal points, and the product's construction supports reliable operation in typical indoor domestic and small-installation environments.

Suitable for

• Powering masthead amplifiers and preamplifiers in residential antenna systems
• Inline installations where remote antenna powering is required without additional cabling
• Small commercial or multi-room setups with F-type coax connections
• Replacement or upgrade of passive feed points to support active antennas

Key specifications

• Connector type: F-type coaxial connector for power insertion and signal pass-through
• Function: DC power injection over coax while maintaining RF signal continuity
• Intended use: Feeding active TV or radio antennas, masthead amplifiers, preamplifiers
• Form factor: Inline device designed for integration into existing coax runs
• Application environment: Domestic and small-installation indoor use

How to use

Install the unit inline on the coaxial feed between the antenna cabling and the receiver or amplifier according to the system layout. Connect the F-type connectors to the coax cable: one side receives the incoming cable from the antenna or amplifier and the other side connects to the downstream device. Ensure the power supply that provides the DC voltage is connected according to the amplifier manufacturer's requirements and that polarities and voltage levels match the masthead device specifications. After installation, verify that the RF signal passes through and that the powered amplifier is functioning correctly.

Usage recommendations

Use with compatible masthead amplifiers and follow the amplifier manufacturer's recommended supply voltage and polarity. Avoid exposing the unit to outdoor elements unless placed within a suitably protected enclosure. Verify cable continuity and connector integrity to minimize insertion loss and ensure reliable power delivery.
