Installing any consumer signal booster setup is fairly simple. There are five steps:

  1. Install Outside Antenna.
  2. Connect to the Amplifier.
  3. Connect all cables.
  4. Power on.

The most “difficult” part is installing the Outside Antenna.

You’ll need some general handyman skills but nothing too specialized. If you prefer having someone else do the job, you can also contact your local general contractor, electrician, or anyone who’s installed a satellite TV dish.

Let’s start:

  1. Find The Best Outside Signal: egin by finding the best signal outside your house. This is done by walking around the perimeter of your home and either using the number of bars on your phone (ok method), smartphone apps (good method), or Field Test Mode (great method) to find the best location. Pro tip: Locating the side of your home getting the best signal is the MOST CRUCIAL step of the installation process.
  2. Install Outside Antenna: The area with the best signal is where you will mount the Outside Antenna. Place the antenna as high up as possible, ideally on the roof, although the fascia or gable is acceptable. It’s important that the Outside Antenna should be on or near the edge of the roof pointing away from the house to the cell tower and NOT pointing across the roof since it may cause interference with the Inside Antenna.
  3. Connect to Amplifier: Once the Outside Antenna is mounted, connect the included RG-6 cable to the Outside Antenna and to the “Outside Antenna” port on the amplifier. Some run cable into the attic, others prefer using the window-entry cable. It’s all a matter of preference and aesthetics and where you want to locate the amplifier. Pro tip: The amplifier does all the heavy lifting for boosting signal and will get warm. Keep it in a well-ventilated area.
  4. Install Inside Antenna: Once the cable is connected to the “Outside Antenna” port of the amplifier, do the same for the “Inside Antenna” port. Some prefer having the Inside Antenna mounted on the ceiling, others prefer the wall, and some prefer using the stand and placing it in a well-trafficked area. Again, it’s all a matter of preference and aesthetics. The most important point is to have the inside antenna located in the area you need signal the most. Pro tip: Having enough separation between the two antennas prevents oscillation. Make sure there is at least 20 feet vertical or 50 feet horizontal distance between the two.
  5. Power on: Plug in the power supply to the Amplifier and to the wall outlet. The amplifier will sync up and if you see all green lights, then green means GO! Check to see near the inside antenna how much better signal you’re getting. Pro tip: Any post-installation adjustments like relocating the Omni Antenna will require rebooting the amplifier. Simply unplug the power supply for 5-10 seconds and replug to reboot the system.
