COAXIAL CABLE KITS AND ACCESSORIES (continued)

Coaxial Surge Diverter WI-DIV-CCMA (-1 dB loss)

The WI-DIV-CCMA coaxial surge diverter is installed between the antenna and the

wireless unit to reduce lightning surges entering the module.

The WI-DIV-CCMA has an SMA connector and can be mounted directly to the module

- it is suitable for the 450 MHz, 968/900 MHz and 2.4 GHz products. It can be used

for 400MHz products with an SMA connector for added protection, however these

already have an internal surge diverter.

A surge diverter is normally not required where an antenna is surrounded by a lot of

steelwork, as in an industrial plant. The WI-DIV-CCMA is recommended where the

antenna installation is NOT surrounded by steelwork, or in areas of high electrical

storm activity where additional protection is desired.

The WI-DIV-CCMA requires additional weatherproofing if used externally.

If the module is mounted in a high vibration area or if large diameter coaxial cable

(low loss) is being used, then the WI-DIV-CCMA should not be mounted directly onto

the module. In these circumstances a short coaxial “tail” should be inserted between

the module and the WI-DIV-CCMA.

The WI-DIV-CCMA will only work effectively with a good ground connection. The

ground connection on the CSD, and the ground connection on the wireless module

must be connected together. The common ground should be connected to the same

ground point as the antenna mounting.

Warning: Do not stay near operating equipment during an electrical storm.

The surge diverter will not provide protection to personnel.

ANTENNA MOUNTING ACCESSORIES

Collinear Mounting Brackets WI-BR-CLR-KIT

The Collinear antenna requires two mounting brackets to hold the antenna in position.

The bracket assemblies consist of 1xU-Bolt 3xD-plates with nuts and washers in each

set. The brackets are zinc plated mild steel.

This simple method of mounting provides a solid support that will support the antenna

for many years.

This mounting provides an excellent earth to the main pole. This pole should prefer-

ably have a low resistance to ground.

Mounting brackets may be replaced if the antenna is dismantled for maintenance.

The brackets are suitable for pole sizes up to a maximum 2" (50mm) in diameter.

Yagi Mounting Bracket WI-BR-YAGI-KIT

The Yagi antenna requires a single mounting bracket. The bracket assembly consists

of 1xU-Bolt 1xD-plate with nuts and washers. The brackets are zinc plated mild steel.

This simple method of mounting provides a solid support that will permanently support

the antenna.

This mounting also provides an excellent earth to the main pole. This pole should

preferably have a low resistance to ground.

Mounting brackets may be replaced if the antenna is dismantled for maintenance.

The brackets are suitable for pole sizes up to a maximum 2" (50mm) in diameter.
