How do I connect an external 4G antenna to my router?

Many factors affect the performance of a 4G connection. Weak 4G coverage can be improved with external antennas, which provide a more stable internet connection at home. You can find tips on choosing an external antenna in our article focused on selecting a 4G antenna here.

In addition to an antenna, you will need a 4G modem/router to boost the 4G signal and create a Wi-Fi connection in your home. The modem receives the 4G signal and distributes it to devices using Wi-Fi.

A 4G router will have either one or two antenna connectors. The connector can be either an SMA or TS9 connector. Routers typically have two SMA female connectors for connecting external antennas. Some newer 4G routers have TS9 connectors, and small-sized dongles often come with miniature connectors (TS9) as well. It is possible to install a 4G antenna on TS9 connector routers and dongles with SMA / TS9 adapter cables.

4G routers with SMA connectors:

- Unscrew the router's approximately 15 cm antennas from the SMA connectors and connect the external antenna cables to the router's SMA connectors. (All Kotiantenni 4G antennas come with SMA connectors)

4G routers and dongles with TS9 connectors:

- Check if your router has one or two TS9 connectors. Routers with two connectors support MIMO technology. Even one external antenna improves the 4G connection, so it is possible to enhance the internet connection even if the router has only one antenna connector.
