Compact white amplifier with downward-facing coaxial port and included power adapter

Antronix

Antronix MRA1-15AC Amplifier 15dB 5-1002MHz + Power Adapter

SKU CH-68KM-26CSD

A single-output TV antenna amplifier with 15 dB gain across 5–1002 MHz, auto-seizing F-ports rated above 2,000 grams contact pressure, and surge protection without arc gaps

  • Key featuresUniversal
  • Compact micro-housing simplifies wiring in NID enclosures
  • 15 dB gain amplifies weak signals across 5-1002 MHz range
  • Patented CamPort auto-seizing F-port delivers 2000 grams contact pressure
  • True 5-42 MHz return band enables full upstream bandwidth
  • Surge protection on all ports without arc gaps reduces impulse noise

Micro-housing amplifier for tight enclosures

The Antronix MRA1-15AC is a single-output distribution amplifier built for subscriber-premise installation. Its downward-facing port layout simplifies coaxial wiring inside NID enclosures or other compact spaces. The unit suits installers who need a small-footprint amplifier that works both indoors and outdoors.

Passive thermal design with surge-rated ports

The amplifier operates without a fan, relying on its metal housing to dissipate heat silently. Patented CamPort® F-ports auto-seize with more than 2,000 grams of contact pressure for reliable connections. Surge protection on all ports handles repeated 6 kV combination-wave events without arc-gap noise, and self-resetting circuitry guards against short circuits.

Power adapter included for immediate deployment

A dedicated power adapter ships in the box so the amplifier can be energised straight away. No extra cables, mounting brackets or configuration software are bundled. Buyers who need multi-output distribution or integrated signal metering will need a different amplifier model.

Questions about this item

How do I install the Antronix MRA1-15AC amplifier in a NID enclosure and what step is often missed?

Mount the micro-housing so all output ports face downward for easier coaxial wiring in tight NID enclosures. The step often missed is tightening each F-connector until the patented CamPort® cam mechanism engages, delivering over 2,000 grams of contact pressure on the center conductor for a reliable seal.

What maintenance or replacement will the Antronix MRA1-15AC amplifier need over time?

The amplifier includes self-resetting circuit protection that clears short-circuit faults automatically, reducing the need for fuse replacements. Its surge protection on all ports operates without arc gaps, so there are no arc-gap components to degrade or replace after repeated high-power surge events.

What is the first performance limit that appears when the Antronix MRA1-15AC amplifier runs continuously at full load?

The downstream spectrum extends to 1,002 MHz and the return band covers 5–42 MHz, so the first limit under sustained use is the available bandwidth ceiling at 1,002 MHz. The 3 dB noise figure and 15 dB gain remain stable within this range, but signals above 1,002 MHz cannot be amplified.
