The Alpha 40 has been tuned to give maximum gain at 4G (2600MHz) frequency but only slightly lower gain at 2G (1700-1900MHz) and 3G (2100MHz) frequencies.
The antenna has sticky pads to mount it wherever it is required. The pads ensure there is a small gap between the antenna and the surface it is to be mounted on.
The Alpha 40 is supplied with different length cables and SMA Male
connectors. Alternative cable lengths and connectors can be specified for volume orders.
