Description
This compact 2G/3G monopole helical terminal antenna supports wide cellular coverage from 824MHz to 2170MHz, delivering stable performance when mounted on a suitable ground plane. It is designed for space-constrained devices that still require dependable cellular connectivity, including NTN (Non-Terrestrial Network) use on Band 255 (Global), Band 256 (Europe), and Band 23 (North America).
- Compact terminal antenna for embedded devices needing an external connector-mounted solution
- Wideband 2G/3G cellular support across multiple global bands
- Ground-plane dependent design for optimal radiation and efficiency
Connector & Cable
- Connector Type: Straight RP-SMA(M)
Installation / Environmental
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.
