The ALPHA 40 4G/3G/2G cellular antenna is tuned to give maximum gain at 4G (2600 MHz) frequency. It has only slightly lower gain at 3G (2100 MHz) and 2G (1700-1900 MHz) frequencies. The ALPHA 40 can also be used for Bluetooth and WiFi applications.

The antenna has two sticky pads to mount and ensures that there is a small gap between the antenna and the mounting surface.
