Zebra Confidential

7.2 Vertical Diversity Mounting

Outdoor installations requiring the maximum location accuracy and

consistency should use vertical and horizontal diversity for antenna placement

should be implemented. This applies to most Yard and Marine Terminal

Sites. Zebra offers three different vertical diversity cable kits for installation.

For all installations, it is recommended that the Right antenna be higher than

the Left Antenna. Consult instruction sheet included in each kit and

WhereLAN III Installation Guide D1677 for further installation information.

1) Antenna Extension

Cable Kit,

CBL-010-10

, which is a 5ft cable kit is

typically used for Yard Sites.

2) Antenna Extension Cable Kit, CBL-015-10 a 15ft. standard cable kit is

used for Marine Terminals.

3) Cable Kit CBL-015-11, Low Loss Antenna Extension, Location Sensor,

15ft may be used for Marine Terminals.

The most critical item in placing and installing the Location Sensors is to

ensure that the antennas are not blocked by nearby structures. Detailed

instructions with several examples are provided in the Location Sensor

Placement Guide D0406.

For accurate locate performance, the position of the left and right antennas

must be individually specified in the site design. System Builder requires the

center point and orientation of the antennas.

The left and right antenna must be correctly oriented per the site design.

Inadvertently reversing the left and right antennas results in a two foot

location error in standard diversity configurations and greater error in

vertical diversity configurations.
