Introduction

Amplifiers increase weak antenna signals so HD channels appear clearly. Mount the device close to the antenna and run quality coax cable to the TV. Check local signal strength before buying.

Adjustable gain prevents over-amplification that can distort channels.
Low-noise circuitry keeps picture and sound free of static.
Multiple outputs let you split the boosted signal to several TVs.

Scan for channels again after installation to lock in the strongest stations.

Introduction

FAQs

Install it between the antenna and the first splitter, ideally outdoors or in an attic. Keep cable runs short to limit signal loss.

These amplifiers are designed for over-the-air antennas. Cable and satellite systems already carry amplified signals and may not need extra boosting.

Most models provide two to four outputs. Use a distribution amplifier if you need to feed more sets without losing strength.

Choose a weatherproof housing if mounting outside. Indoor units work fine in dry attics or crawl spaces.

Yes, connect both antennas to a combiner first, then feed the combined signal into the amplifier for balanced boosting.
