Description
The TG.22.0111 is a compact monopole helical terminal antenna designed for 2G/3G cellular operation across a wide range of global bands. When mounted to an adequate ground-plane, it delivers stable performance in a small, rugged form factor—ideal where larger antennas cannot be used.
- Wideband 2G/3G coverage: supports multiple GSM/UMTS/CDMA-related standards in one compact antenna
- Ground-plane dependent design: optimized for terminal mounting on a device ground-plane
- Compact and robust: suited to space-constrained telematics and monitoring devices
- NTN support guidance: recommended for NTN devices operating on Band 255 (Global), Band 256 (Europe), and Band 23 (North America)
Typical use cases: Remote monitoring, telematics devices, NTN (Non-Terrestrial Network) devices.

- Connector Type: SMA-M
Installation / Environmental
At only 49mm in height, with a hardened TPEE casing, this antenna is the ideal GPRS/UMTS antenna for telematics devices where larger antennas cannot be used. Like all small monopole antennas, it must be mounted on a ground-plane to radiate efficiently. The antenna should be mounted at the edge of the ground-plane of the mainboard of the device. See below charts for analysis of performance. A larger ground-plane of more than 100mm is needed for stable performance on all bands. Also no metal should be used near the antenna, with at least 20mm of clearance required, the more clearance the better. For devices with ground-planes smaller than 100mm in length or where metal clearance is not adequate, alternative larger antennas should be considered such as the TG.30. If small size is needed, a custom tuned solution or a new design may also be necessary. Contact your regional sales office for support.
