Colinear GSM Antenna

Quick Overview

Colinear GSM frequency antenna for wall mounting with an extra strength reinforced bracket. The COLGSM is an omni-directional antenna suitable for use with most GSM & GPRS devices with a radio band frequency from 868MHz to 915MHz. Standard options are 5 and 10m of cable with an SMA connector. Other standard radio connectors and cable lengths are available on request.

A colinear (or collinear) antenna consists of a number of smaller 'antennas' mounted in such a way as to allow the corresponding elements in each to be parallel and colinear, that is located along a common line or axis. Colinear antennas are high gain omni-direction antennas with an omni-directional radiation pattern when in free space. The antenna radiates equal radio power in all azimuthal directions perpendicular to the antenna. Stacking multiple 'antennas' in a vertical colinear array increases the power radiated in horizontal directions and limits the amount of power that is being radiated into the ground or up into the sky.

The COLGSM is a cellular base station antenna with a GSM frequency range of 868 to 915MHz. The antenna is supplied with a reinforced extra strength wall bracket. The COLGSM antenna is ideal for improving the GSM and GPRS communications on the GRD and OmniText GSM/GPRS data logger/SMS alarm units and any other radio devices that use the 868 to 915MHz frequency bands.
