MATCHMASTER VHF TWIN 7MHZ CHANNEL AGC AMPLIFIER : 14MM-AT422

Description

Stable RF Performance for Professional Headend Systems

Designed for licensed electricians and AV integrators, this dual-channel VHF channel amplifier delivers consistent signal performance across demanding installations. With two internal channel amplifiers and independently set 7MHz bandwidth per channel, it supports precise signal control for Australian channel allocation systems.

The built-in AGC (Automatic Gain Control) helps maintain stable output levels, reducing signal fluctuation across connected systems. With a full RF frequency range of 470MHz to 862MHz and output level up to 85dBµV, it supports reliable distribution in residential, commercial, and facility headend environments where signal integrity is critical.

Built for Compliance, Stability, and Long-Term Reliability

Engineered for Australian broadcast requirements, this amplifier provides selectivity of -40dB at ±2MHz from the 7MHz filter edge, ensuring clean channel separation and reduced interference. A noise figure of 8dB and return loss greater than 10dB at output further supports stable system performance in structured RF networks.

The unit is designed for operating environments from 0°C to +50°C, making it suitable for plant rooms, comms racks, and building infrastructure installations. Loop-through connectivity on both input and output allows cascading across multiple modules, supporting scalable system design without compromising signal quality.

Trade-Friendly Installation and System Integration

Built for efficiency on-site, the 14MM-AT422 features push-button programmable channel selection with LED display feedback for fast setup and commissioning. Its 1RU rack-mount design makes it ideal for structured rack installations where space and accessibility matter.

Loop-through F connectors simplify cascading between modules, reducing rewiring time and supporting faster headend build-outs. With 12V masthead amplifier supply capability and low-voltage operation, it integrates easily into existing RF infrastructure used by contractors and maintenance teams.

Bulk packing helps reduce transit damage risk, supporting safer delivery for busy electrical projects where downtime must be avoided.
