The yagi antenna REQUIRES line of sight to the tower (it will not work if you don't know where the tower is or if there are obstructions between you and the tower). The panel antenna is also a directional antenna and must be aimed towards the tower, but it does NOT require line of sight. If you are not sure where the cell tower is, you should choose one of the omnidirectional antennas (however, using an omnidirectional antenna will require more separation between your exterior and interior antennas, so make sure you purchase enough cabling and plan your installation accordingly).
Select External Antenna (required) - details
This cable will go between your outside antenna and the amplifier. Make sure you buy enough cable to accommodate your installation, keeping in mind the separation requirements for this amplifier!
Select Cable from Outside Antenna to Amp (required) - details
Select an inside antenna to rebroadcast the boosted signal. The DOME antenna mounts to a ceiling and provides an "omni" type of coverage area. The PANEL antenna can either be mounted on a ceiling facing downward (like the dome antenna) or on a wall facing outward (to direct signal in a certain direction). The panel antenna typically covers more area than the dome and is usually the better choice.
Select Inside Antenna (required) - details
This cable will go between the amplifier and your inside antenna. Make sure you buy enough cable to accommodate your installation, keeping in mind the separation requirements for this amplifier!
Select Cable from Amp to Inside Antenna (required) - details
A surge protector goes in between your outside antenna and the amplifier and protects your amplifier if lightning strikes your antenna. It's not required but is recommended for users in areas where lightning strikes frequently.
Add Lightning Protection (optional) - details

Fast Facts About This Product:

  • This amplifier is best for: Users who need to provide amplified cellular signal to multiple cellular modems/phones on CANADIAN networks in a office/warehouse environment and have the space to accommodate the 100-150' of separation between the outside and inside antennas that this kit requires.
  • All-in-One Kit? NO - antennas and cabling are required (sold separately), see above
  • Coverage area*: 20,000-60,000 square feet
  • Compatibility: This amplifier supports 700mhz/800mhz/1700mhz/1900mhz/2100mhz networks (which includes most 2G, 3G, and 4G providers in Canada as well as most 2G/3G providers in the US). Supported carriers/networks include:
    • Rogers 2G/3G/HSPA+ (NOT LTE)
    • Bell 2G/3G/4G
    • Verizon 2G/3G and 4G only where Verizon is using the AWS bands (in most cases, Verizon users will be better off going with a 700mhz amplifier)
    • Sprint 2G/3G
    • AT&T 2G/3G and HSPA+ (which shows up on your device as "4G" - NOT LTE)
    • US Cellular 2G/3G
    • Datajack and Virgin Mobile 3G
    • T-Mobile 3G/4G
    • MetroPCS 3G/4G
    • Does NOT work with any 4G LTE networks in USA nor Rogers' 2600mhz LTE network, WiMAX, or Nextel/I-Den.

Do a site survey before buying this amplifier! If you're purchasing this to use in just one location, we strongly recommend doing a site survey first to determine whether the amplifier will help your signal and performance and to give you an idea of what kind of results you can expect from it. Start here: Will an Antenna/Amplifier Help Me?

If your signal is extremely poor (-108db or worse), an amplifier may not help you. There must be some usable signal available for the amplifier to boost for it to be effective.

Built with High Linearity, this amplifier combines PCS and Cellular dual-bands with the  LTE and AWS frequencies used in Canada as a total cellular amplification solution for Canadian users. This full-featured amplifier includes adjustable gain control and automatic shutdown for maximum flexibility. Extremely competitively priced, it requires 1/5th the space requirements and is a fraction of the cost compared to similar amplifiers with its capabilities. Ideal for locations with a low cellular signal and/or requiring large coverage. Covers up to 80,000 square feet (4,700m2) with good signal.

How it works: The outside antenna (sold separately) picks up the cellular signal and sends it through a cable (sold separately) to the amplifier. The signal is then boosted and sent through a cable (sold separately) to the inside antenna (sold separately), which rebroadcasts the boosted signal. All of your modems/phones within range of the inside antenna can benefit from the boosted signal wirelessly.

*Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

Installation notes:

  • In order for your system to function properly, you must maintain adequate separation between the outside and inside antennas (if the antennas are too close together, there will be oscillation/feedback between the antennas and the amplifier will shut down). This amplifier requires approximately 100-150' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • If you cannot achieve adequate separation to eliminate oscillation, you can turn down the gain on the amplifier, but that will result in a smaller coverage area from the amplifier.
  • The interior antenna should be at least 10' away from the amplifier.
  • If you are using a panel antenna as the interior antenna, make sure it is aimed AWAY from the outside antenna.
