Installing an Antenna / Aerial

A poor antenna installation can greatly reduce the reliability of 4G / 5G data comms.

Here are some general pointers to help you to install an antenna successfully. This guidance actually applies to any type of antenna, including (for example) WiFi antennae:

  • Mount the antenna vertically. (Any other orientation is worse than useless).
  • Avoid the antenna touching any surface.
  • Keep cable extensions to a minimum length. As a rule of thumb, every additional meter of cable reduces the signal quality by 1 dBm.
  • Reduce / avoid a situation where the antenna is surrounded by metal, including metal enclosures,building fabric and cable tray.
  • Avoid kinking or squashing the relatively fragile coax cable. Coax can become damaged over an extended period of time by kinking or squashing, even it it works when it is first installed.
  • Where possible, if the antenna is “outdoor rated”, mount the antenna outdoors.
  • Mount the aerial as high as possible.

If you are still having problems achieved a good connection, please reach out to our support to enquire about a High Gain or Directional antenna.
