IRepeaters LineAmp L3-O (800 / 900 / 1800 MHz)

Professional Line Amplifier for Mobile Signal Boosters

The IRepeaters LineAmp L3-O is a powerful, professional-grade line amplifier designed for communications engineers, system integrators, and advanced installers. Built to enhance mobile repeater performance, this line amplifier strengthens signal travelling through long coaxial cable runs—making it an essential upgrade for large buildings, marine vessels, commercial sites, and demanding multi-antenna installations.

How the LineAmp Works

The LineAmp is installed between the main repeater and the internal antennas. Its core function is to boost the mobile signal along the cable, compensating for loss caused by long cable distances or multi-antenna distribution systems.

With an impressive +20 dB of additional gain, the LineAmp:

  • Strengthens the signal before it reaches your indoor antennas
  • Improves clarity and stability
  • Enables longer coaxial cable runs without losing performance

This extra gain increases the coverage reach by up to 100 meters, ensuring reliable mobile connectivity even in long-range indoor or shipboard applications.

Versatile Multi-Antenna Coverage

The 4-port LineAmp model allows you to connect and power up to 6 indoor antennas, delivering amplified signal to multiple indoor zones simultaneously.

This makes it the ideal solution for:

  • Large office buildings
  • Multi-deck ships
  • Warehouses
  • Hotels, schools & commercial complexes
  • Multi-room repeater installations

The result: strong, consistent coverage across all zones with reduced signal loss and no dead areas.

Why Choose the LineAmp?

Superior Signal Boost

Adds +20 dB of gain to compensate for cable loss, boosting repeater performance dramatically.

Extended Coverage Range

Pushes mobile signal deeper into your building or vessel with an additional 100 meters of effective reach.

Multi-Area Output

The 4-port model distributes signal to four different areas, ensuring complete and balanced coverage.

Professional-Grade Design

Engineered for advanced repeater setups, large installations, and high-demand environments.

Available LineAmp Models

  • L3-O800 / 900 / 1800 MHz

Frequently Asked Questions

It’s a device that boosts your current weak 2G 3G 4G AND 5G signals and then delivers the stronger signal to your cell phone.

  1. Outside Antenna: Pulls in the existing signal from the cell tower and sends it to the amplifier.
  2. Amplifier: Boosts that signal multiple times and sends it to the inside antenna.
  3. Inside Antenna: Broadcasts the boosted signal to the area in need.

Yes. Cell phone signal boosters work with ALL mobile phones that use any variation of 3G or 4G and service.

Yes. Our boosters work with all major North American carriers in Ireland (Vodafone,Eir, Three,Lyca,Tesco,48 Mobile, Clear Mobile,sky and Virgin.). For a more thorough list please email us at [email protected]

For a complete explanation of frequencies and a simple chart, see our Frequencies by Provider article.

Cell phone signal boosters generally come in two categories: for buildings such as homes and offices and for vehicles such as cars, Trucks and boats.

Absolutely.

Signal boosters for homes and offices boost 3G & 4G LTE and 5G signals inside the building. Although you may get some coverage outside the building, they are not designed for this purpose. They are generally fixed installations and powerful performers.

Signal boosters for cars, trucks, RVs, and boats boost 3G & 4G LTE and 5G signals inside your vehicle (usually a range of 5-8 feet). Some units can be used indoors with additional accessory kits.

Whether you’re looking for something affordable, commercial-grade, or custom, we provide a variety of solutions. Start with our Buyer’s Guide to get our best recommendations.

No, you don’t need an internet connection, but you do need an existing cell phone signal. If there is no existing signal, then you’re in a no service dead zone, meaning the amplifier cannot boost what isn’t there.
