How to Properly Connect and Mount Signal Booster Antennas

Proper antenna connection is crucial for the optimal performance of your signal booster. Incorrect installation can lead to poor signal reception, auto-oscillation, or reduced coverage. Follow this guide to correctly connect and mount the external and internal antennas in your system.

What’s Included in a Standard Kit?

A typical signal booster kit consists of the following components:

 External Antenna – can be:

  • Log-Periodic directional antenna (LPDA) for home boosters.
  • Magnetic Omni-directional Antenna for vehicle boosters.
  • High Gain Pipe Antenna, an omni-directional antenna for outdoor installation, pointing to sky vertically, donot care cell tower direction..

Internal Antenna – can be:

  • Ceiling or Panel Antenna (connected via cable).
  • Patch Antenna for car or boat.


External Cable – connects the external antenna to the booster.
Standard lengths range from 15 meters, but can be adjusted as needed.

Signal Booster Unit – The core device that boosts the signal.

Internal Cable – Connects the internal antenna to the booster. Standard length is 5 meters, but can be extended if needed. 

Understanding Booster’s Antenna Ports

Different booster models have different port labels. Here’s what they mean:

  • Outdoor – Connects to the external antenna.
  • Indoor – Connects to the internal antenna(s).
  • DC – For power supply connection.

Attention! To prevent signal oscillation, it is important that the two antennas have at least 3-5 meters of separation.

Ensuring Proper Antenna Isolation Before Turning On

Before turning on the booster, check for proper antenna placement to prevent auto-oscillation issue (feedback loops) and interference:

 Maintain a minimum distance between antennas:

  • Outdoor to Indoor Antenna: At least 5 meters horizontally and 1.5 meters vertically. If the outdoor signal is strong, it’s recommended to increase this distance. A stronger input signal requires a greater separation for optimal performance.
  • Indoor to Indoor Antenna: At least 3-5 meters apart to avoid signal interference. If your coverage area is small and the distance between 2 indoor antennas is less than 5 meters, use only one indoor antenna to avoid signal interference.

 Position antennas correctly:

  • Best placed on the roof with a clear line of sight to the nearest cell tower.
  • Never place the outdoor and indoor antennas facing each other.
  • Use obstacles like walls, ceilings, or metal barriers to block direct signal paths.
  • Aim antennas in opposite or distinctly different directions.

* For detailed instructions on how to aim and position the external antenna properly, refer to Position and Aim External Antenna Correctly

How to Mount the Antennas

Mounting the external antenna

LPDA Antenna:

Should be installed on a pole.

Make sure the antenna is mounted vertically and the red arrow on the antenna case points upward.

Panel Antenna:

  • Can be wall-mounted or pole-mounted.
  • Position it as high as possible for the best signal reception.

Pay attention to the vertical position of the panel antenna. The cable should go down.

Mounting the Internal Antenna

Ceiling Antenna:

  • Best for large open spaces, homes, or offices.
  • Place it in the center of the area for even signal distribution.

Panel Antenna:

  • Ideal for long, narrow spaces (corridors, hallways, etc.).
  • Mount on a wall, just like an external panel antenna.
  • Aim it toward the area where signal improvement is needed.

Tips for Best Performance

  • Avoid excessive bending or pinching of the cables. to ensure optimal signal transmission.
  • If excess cable remains, carefully roll it or shorten the cable.
  • Insulate external connectors from moisture using standard electrical tape for better protection.
  • Check connectors for integrity during system assembly to prevent connection issues.
  • If experiencing interference, adjust the antenna positions slightly to find the best configuration.

Install more internal antennas

In case there are many rooms and walls in your property, you may need to install more than one internal antenna to eliminate blind spots. You can choose extra internal antennas and extra cables needed in your order. We will prepare free splitter and enough cables to fit your needs.
