Can the cable be too long?

Yes. The longer the antenna cable, the greater the signal loss can be between the antenna and the router.

So a very long cable can in some cases reduce the effect of a good antenna, especially if the cable has high attenuation or is of lower quality.

Keep the following in mind

For the best result you should:

  • use a cable as short as the installation allows
  • avoid unnecessary extensions
  • use cables intended for 4G/5G
  • avoid sharp bends and pinched cables
  • check that all connectors are firmly attached

When installing a roof antenna it is therefore worth planning the position so that the cable route to the router is as short and straight as possible.
