Antenna power inserter MONTIS MT084/01 — universal inline power supply for antenna systems

MONTIS MT084/01 is a compact antenna power inserter designed to inject DC power into coaxial cable runs, supplying active antennas and masthead amplifiers without altering the antenna or receiver connections. The inline unit fits between the antenna and receiver, allowing convenient remote powering of active elements for terrestrial TV, FM and similar coax-fed installations. Its universal design supports common coax systems and simplifies installation where a dedicated power feed is required.

Advantages

The device provides a simple, space-saving solution for remote powering of active antenna elements through the same coaxial cable used for signal transmission, avoiding additional wiring. Its inline form factor enables quick insertion into existing antenna setups without modifying cables or connectors. The unit is compatible with typical terrestrial TV and FM antenna systems and is suitable for use in both new installations and upgrades of existing coax-fed equipment.

Suitable for

• Supplying DC power to masthead amplifiers in terrestrial TV installations
• Powering active FM antennas and signal boosters
• Remote powering of outdoor or roof-mounted antenna elements via coax
• In-line DC injection in retrofit or temporary antenna setups

Key specifications

• Inline design for insertion between antenna and receiver
• DC power injection over coaxial cable to active antenna components
• Suitable for terrestrial TV and FM coax-fed antenna systems
• Compact housing to minimize space requirements in installation points

How to use

Install the MONTIS MT084/01 inline between the antenna feed and the receiver or distribution point, ensuring connectors are properly mated. Connect the DC supply to the designated power input on the inserter according to the supplier instructions, then verify that power reaches the active antenna element or masthead amplifier. After installation, check signal reception and confirm that the powered device is functioning correctly. If necessary, power down before making connector changes to avoid short circuits.

Usage recommendations

Use appropriate coaxial cable and connectors rated for the installation environment, and ensure the DC supply voltage and polarity match the requirements of the active antenna or amplifier. Avoid exposing the inline unit to prolonged moisture or direct water ingress; install in sheltered locations or use weatherproof enclosures where required.
