SECTION 5
MAINTENANCE
5-1 Scheduled Maintenance
The antenna is virtually maintenance free. The external finish is a silicone alkyd paint. The
minimum finish life before showing signs of deterioration should be at least six years under
normal climate conditions.
When used in salt-water environments, it is recommended to wash the antenna base with
fresh water to remove any build-up of dried salt residue. This must be performed on a
monthly basis, when exposed to sea-spray.
Use a small wire brush to clear any debris from the drain groove found in the bottom of the
antenna base.
All threaded hardware, including the base mounting bolts, the countersunk screws at the joint
and the input power connector should be inspected for signs of damage and to ensure proper
tightness (suggested torque settings can be found on pages 8 and 9). In most cases a quick
visual inspection is all that is required. This must be performed on a monthly basis or
whenever practical.
5-2 Corrective Maintenance
5-2.1 General Repairs
Generally, no corrective maintenance is possible or required. If one section is severely
damaged, it must be replaced by a new section. Workshops having experience in handling
epoxy fibreglass composite structures and/or aluminum construction may attempt the repair
of minor surface damage if practicable.
NOTE
DO NOT USE LEAD BASE PAINT TO TOUCH-UP OR REPAINT
THE ANTENNA. USE ONLY EPOXY BASE PAINT.
