4G / 5G Twin Antenna Extension Cable | SMA Male to SMA Female (5m, 10m)

Is your antenna cable too short? Solve the problem without cable clutter using this Twin extension cable for LTE and 5G. Many outdoor antennas come with short, permanently attached cables. This dual cable (two lines in one string) cleanly extends your MIMO connection all the way to the router. Equipped with SMA-Male to SMA-Female connectors, you simply click it between your existing cable and the router. Available in 5m and 10m lengths, it offers an excellent compromise between flexibility and low signal loss.


Highlights

  • True Extension: SMA-Male to SMA-Female – connects directly to the existing cable of your antenna.
  • 2-in-1 Design (Twin): Two cable strands firmly connected together (MIMO compatible).
  • Selectable Lengths: Available in 5m and 10m – get exactly the reach you are missing.
  • Good Compromise: The coaxial cable has low attenuation but is still easy to route with approx. 5mm per strand.
  • Universal: Compatible with almost all standard 4G/LTE and 5G routers & antennas (SMA standard).

The Perfect Extension Cable for MIMO Antennas

Often, the included cable of an LTE or 5G outdoor antenna barely reaches inside the house, but the router actually needs to be placed one room further or on the ground floor.
This is where our Twin Extension Cable comes into play. Instead of having to route two separate extension cables crisscrossing your home, you use this bundled cable strand. It transmits both signals of the MIMO technology (Multiple Input Multiple Output) cleanly and neatly.

Simple Plug & Play

This cable is equipped with two SMA-Female jacks on one end and two SMA-Male plugs on the other end.
You simply screw the connectors of your antenna into the female jacks of this extension cable. The male connectors on the other end then go straight into your router (e.g., Teltonika, FritzBox, Huawei). It doesn't get any easier!

Which Length Do You Need?

Every cable extension "swallows" some of the antenna signal (attenuation). Therefore, the rule of thumb is: As short as possible, as long as necessary. Choose between:

  • 5 Meters: The ideal standard extension for the path from the windowsill to the desk.
  • 10 Meters: For longer distances, e.g., if the antenna is mounted on the roof and the router is in the living room.

The cable was a bit stiff, and unfortunately it wasn't quite 5m long, only 4.30m, but it was sufficient. On the plus side, the signal is transmitted 1:1, which is also desirable.

Unfortunately, I can't do without it, and the cable is integrated directly into the antenna... but everything's fine!

Kabel etwas steif leider waren es auch nicht ganz 5m sondern nur 4,30m aber es hat gereicht
Positiv ist das das Signal auch 1zu1 weiter geleitet wird was auch wünschenswert ist
