GSM Antenna Specifications


This article lists the 3 kinds of antenna specifications, which mainly supports for the TG series gateway products.

Scope of application: TG-Series Gateway, U-Series VoIP PBX, S-Series VoIP PBX

1. The Four-in-One Antenna

Supported devices: TG400, TG800, TG1600 (hardware version V1, V2, V3)

Frankly speaking, the Four-in-One Antenna is the power divider that must built in the TG-Series gateway device. The built-in RF line should plug into the GSM module, and the other end is installed on the shell of the equipment, it’s used for the antennas installation.(long antenna).

The power divider implements Four-in-One function. If it is implemented on TG800, two power dividers should be installed in the device.


Four-in-One Antenna is optional part from origin. If you want to use it, you had better explain this point to the Sales in the corresponding region when purchasing equipment.
