External Antennas; Antenna Cable Extensions Recommendation - Allen-Bradley Stratix 5100 User Manual

External Antennas

The Stratix 5100 Wireless Access Point/Workgroup Bridge has external antenna
connectors and a status indicator on the top. The antennas are rugged and
designed for industrial use in locations such as hospitals, factories, warehouses,
and other locations where there is a need for extended operating temperatures.
The external antennas support mounting inside NEMA enclosures for use in the
most demanding environments.
The Stratix 5100 WAP is configured with up to four external dual-band dipole
antennas, and 2.4 GHz and 5 GHz dual-band radios in a 3 x 4 multiple-input/
multiple-output (MIMO) configuration with three spatial streams. The radios
and antennas support frequency bands 2400...2500 MHz and 5150...5850 MHz
through a common dual-band RF interface.
The following Cisco antennas are supported on the Stratix 5100 WAP:

configuration of the equipment that results in a total output power level
(eirp) below the applicable regulatory limit. An incorrect configuration can
result in an output power level (eirp) level above the regulatory limit.
Antennas must be mounted indoors only.

Antenna Cable Extensions Recommendation

Keep antenna cable runs as short as possible. Cisco offers low loss (LL) and
ultralow loss (ULL) cables, that have the same characteristics as Times
Microwave LMR-400 and LMR-600. When drilling holes for cable, allow for the
size of connector drill bit, typically15.8750 mm (5/8 in.).
Cisco cables carry the part number AIR-CAB (Aironet Cable) and then a length.
For example, a 20 ft length of LL cable with RP-TNC connector is
Cisco AIR-CAB-020LL-R. These heavy black cables are not plenum rated and
are primarily for use in manufacturing areas.
