Product information

Description

The Triax MFA657 is a compact TV signal amplifier designed to operate in the 470–694 MHz frequency range. Equipped with F-female connectors, this mast amplifier boosts received TV signals to improve reception quality in locations with weak or marginal signal levels. Its compact housing (137 mm × 60 mm × 115 mm) makes it suitable for installation on masts or in small technical enclosures.

Advantages

The MFA657 provides multiband amplification optimized for UHF television bands within 470–694 MHz and includes channel cut-off options to limit unwanted frequency ranges. F-female connectors allow straightforward cabling and compatibility with common TV coaxial cables. The unit’s small footprint simplifies mounting and integration on standard masts.

Suitable for

Residential rooftop or mast installations to improve TV reception
Small communal antenna systems requiring a compact mast amplifier
Locations with weak or variable UHF broadcast signals

Key specifications

Frequency range: 470–694 MHz
Connector type: F-female
Dimensions (W × D × H): 137 mm × 60 mm × 115 mm
Multiband amplifier with selectable channel cut-off ranges

How to use

Mount the amplifier on the mast or in a protected technical box close to the antenna feed. Connect the antenna coaxial cable to the input F-female connector and run an output coaxial cable from the amplifier to the distribution point or TV. Ensure power is supplied according to the amplifier’s installation instructions and verify signal levels after installation to avoid overloading downstream equipment.

Usage recommendations

Install the MFA657 as close to the antenna as practical to minimize signal loss in the feed cable. Use quality coaxial cable and connectors, and adjust or disable amplification if downstream signal levels exceed receiver tolerances.
