10. MAINTENANCE AND TROUBLESHOOTING
10-2
Antenna unit
Check the antenna unit yearly for rust, corro-
sion and chipped paint. If the antenna base
has rusted or the paint has chipped, paint the
affected area. Paint only the antenna base.
Do not paint the radome. Paint on the radome
can cause loss of sensitivity and crack the ra-
dome.
Also check the anti-corrosive sealant on the ground bolt for deterioration (peeling,
cracking, etc.) every 3 to 6 months. If the deterioration is minor, re-apply the sealant.
For serious deterioration, completely remove the sealant, then re-apply the sealant.
Water leakage can corrode the bolt if it is not properly treated.
