4 ACCESSORY ITEMS
This section provides a brief description of the accessory items that are available separately for
the SCS system. The accessory items may or may not be required depending on the application.
4.1 Strand Mount Kit for RU
A strand-mount kit is available if the application requires that the RU be mounted from an
overhead cable system. Mounting pads are provided on the side of the RU enclosure for
securing a pair of cable-attachment clips. Screws are used to secure the cable-attachment clips
to the RU enclosure.
4.2 Lightning Protector for RU
An external lightning protector is available separately for the RU. It is recommended that an
external lightning protector be installed at the RU antenna port to reduce the chance of damage
to electronic components should a lightning strike occur. The antenna terminal on the lighting
protector may be equipped with either an N-type female connector or a 7/16 mm DIN female
connector depending on the application requirements.
