for areas that require a higher gain antenna.

4G/3G Cellular Whip Antenna with SMA Connector: A wideband termination
antenna with SMA connector and articulating base. It has a high-efficiency response
on nearly all 4G, 3G, and 2G frequency bands and is, therefore, primarily used with
cellular gateways and routers. This antenna attaches directly to the CELL200 series
and is intended for use inside the enclosure. Please note that the backplate of the
enclosure is a grounded plane. If it is interposed between the antenna and the cell
tower, it may attenuate the strength of the transmission signal. Simply turning the
enclosure 90 to 180 degrees on its mounting mast may solve weak transmission
issues.
TIP:
Cellular phone apps, such as OpenSignal (
), show the direction to
point an antenna to get the best signal strength.
6.3 Wiring and connections
This section explains how to connect the module for different communications methods. It also
describes how to power the module and connect an antenna.
