## Summary description

Antenna power supply providing 12 V DC at 300 mA for powering active TV, FM and DVB‑T antenna amplifiers and mastheads. Compact inline unit with standard coaxial power output designed to feed low‑current amplifier modules, protect against polarity reversal and ensure stable voltage for improved signal reception. Suitable for home and small installation use.

## Long description

A compact antenna power supply delivering 12 V DC at 300 mA designed to feed active TV, FM and DVB‑T antenna amplifiers and masthead preamplifiers. The inline unit connects to standard coaxial cable and provides a stable low-current supply, with built-in polarity protection to avoid damage from incorrect wiring. Intended for residential and small installation use, it helps maintain consistent amplifier operation and can improve signal reception when used with compatible low‑power antenna modules.
Advantages
The power supply offers a compact form factor that installs inline with coaxial feeders and requires minimal space. It provides a regulated 12 V output at up to 300 mA adequate for many small antenna amplifiers and masthead preamps. Integrated polarity protection reduces the risk of damage from reverse connection, and the standard coaxial power connector simplifies compatibility with common antenna equipment. The design emphasizes stable voltage delivery to support continuous signal amplification without introducing complex electronics into the antenna line.
Suitable for
 Powering small TV antenna amplifiers and masthead preamplifiers
 Supplying FM antenna boosters and low‑power DVB‑T amplifiers
 Home and small building installations where a compact inline supply is needed
 Situations requiring polarity protection for coax-fed amplifier modules
Key specifications
 Output voltage: 12 V DC
 Maximum output current: 300 mA
 Connector type: standard coaxial power output for antenna coax
 Protection features: polarity reversal protection
 Form factor: compact inline unit suitable for mounting on coaxial runs
 Intended use: powering active antenna amplifiers and masthead preamps
How to use
Install the unit inline on the coaxial feed between the power source (wall adapter or distribution box) and the antenna amplifier input. Ensure the coaxial connectors are fully tightened and that the power supply is placed in a dry, ventilated location away from direct weather exposure. Confirm that the amplifier or masthead preamplifier requires 12 V and does not exceed 300 mA current draw. Connect the coaxial output to the amplifier and apply power; the built‑in polarity protection prevents damage from reversed connections. Periodically inspect connections for corrosion or looseness to maintain reliable operation.
Usage recommendations
Use this 12 V/300 mA supply with low‑current amplifiers and masthead preamps only. For devices with higher current requirements or long cable runs that cause voltage drop, select a higher‑current or line‑regulated power source. Avoid exposing the inline unit to moisture; if outdoor installation is required, mount it in a weatherproof enclosure and ensure proper grounding of the antenna system for safety and lightning protection.
