Used briefly but upgraded to a directional 4G Mimo antenna setup Now surplus to requirements B4BE-6-60-05SP 2G/3G/4G/5G Low Profile Antenna with 0.5M Cable SMA Connector From the web:

The Panorama B4BE is a robust bracket mount antenna for 5G, LTE, M2M and IoT applications. This is the 0.5m (50cm) Version with SMA Connector

Robust, cost-effective bracket mount antenna integrated cable Supports 2G/3G/4G/5G The B4BE range has been designed to provide cost effective coverage booster antennas for 2G/3G/4G/5G devices. The antennas are designed for wall or mast mounting and are weather proof which allows the device to reap the benefits of an antenna mounted in an elevated or external location where the signal is strongest. The omni-directional radiation pattern allows the antenna to be quickly installed while the global Cellular/GSM/LTE coverage provided by the antenna allows it to be utilised for 2G/3G/4G & 5G applications the world over.
