If mounting the GPS receiver on the equipment building, select a position on the wall that meets the following
requirements:
• It must be below the roof height of the equipment building or below the height of any roof-mounted equipment
(such as air conditioning plant).
• It must be below the lightning air terminals.
• It must not project more than 600mm (24 inches) from the wall of the building.
If these requirements cannot all be met, then the module must be mounted on a metal tower or mast.
