Instead of the Gigaset external antennas, you can connect also third party antennas. Below are the Microset antennas.
Gigaset does not sell these antennas !!!
Always replace both Gigaset antennas with the same external third party antennas, only then the optimum DECT quality is obtained. Some antennas mentioned below have one connector, this means that you need to buy 2 antennas.
Connect both external antennas to maintain antenna diversity
The antennas should be of the same type
Keep at least 30 cm between the antennas
Place both antennas in the same area. One inside and one outside is not supported
Antenna cables should be of the same type and length, keep the length as short as possible
