Scheduled Maintenance

The antenna is virtually maintenance free. The external finish is a polyurethane two part
compound paint. The minimum finish life before showing signs of deterioration should
be at least ten years under normal climate condition.
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 should be performed on a
monthly basis or after prolonged exposure to sea-spray.
Use a small wire brush to clear any debris from the drain groove found in the bottom of
the antenna base. In the case of the FT version, there is a small drain hole located on the
side of the insulator. This hole should be kept clear from blockage using a small length
of stiff wire.
All threaded hardware, including the base mounting bolts, the set-screws at the joint and
the input power connection 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.

Corrective Maintenance

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 may attempt the repair of minor surface
damage if practicable.
DO NOT USE LEAD BASE PAINT TO TOUCH-UP OR REPAINT
THE ANTENNA. USE ONLY EPOXY BASE PAINT.
