1-2 System Overview
Each Link CX consists of a Link CX radio, with integral antenna (5.3 GHz or 5.8 GHz versions) or an
optional external antenna (5.8 GHz versions), as shown in Figure 1-1, along with external power and
data cabling. In a typical installation, the Link CX radio and antenna are mounted outdoors, usually on a
tower or building. If so equipped, the external antenna connects to the Link CX radio through a
factory-supplied coaxial cable.
See Figure 1-1. A radio system, or link, contains two Link CX radios each equipped with either an
integral or external antenna, installed at each end of the link, separated by a line of sight transmission
path. Frequency band, terrain, actual line-of-sight and environmental conditions influence the range of
operation and path performance.
The Link CX carries one full-duplex DS-3 or Ethernet channel, and is powered by a 30-watt external
±21 to ±60 VDC power supply.
