3. Note the current peak ACG value. Press the Tracking key to toggle Tracking OFF, press the RIGHT
arrow key repeatedly to move the antenna up in azimuth until AGC falls about 100 counts. Turn
Tracking ON and verify that the antenna moves back down in azimuth and that the AGC rises to its’
previous high value.

6.4. Monthly Inspections
Regular inspections will assure that your antenna is in peak operating condition. It is possible that your system may
not require any service for over a year. However, to maintain peak operational and to extend the life of the
equipment, some components should be changed annually. Your Sea Tel authorized dealer has trained service
technicians who will perform this work using Sea Tel replacement parts.
Description of Maintenance Operator Check Inspected by Inspection date
1.4.1. Radome Visual Inspection
1.4.2. Pedestal Visual Inspection
1.4.3. Mechanical Checks
6.4.1.
Conduct a good, thorough, visual inspection of the radome. If any damage is found, notify your dealer
immediately.
Monthly Radome Visual Inspection
1. Inspect the outside surface of the radome (top and base) looking for scrapes, cracks, or mars or
residue indicating that the gel coat surface has been impacted, or in any other way, damaged.
Damage to the sealant coat, or core structure of the radome MUST be properly repaired and re-
sealed immediately. If diesel exhaust, or any other residue, is coating the outside of the radome it
should be cleaned with mild soapy water to minimize signal loss due caused by these residues.
2. Inspect the inside surface of the radome (top and base) looking for cracks, mars or white fiberglass
powder residue due to chafing in the material indicating that it has been impacted or scraped or any
other signs of wear or damage.
3. Inspect the flange mating of the radome top and base to insure that the flange is properly sealed to
prevent wind, saltwater spray and rain from being able to enter the radome.
4. If condensation, or standing water, is found inside the radome, isolate and seal the leak, and then
dry out the radome. Debris clogging the small weep holes in the recessed areas of the radome base
may need to be cleaned out to allow standing water to “weep” out. DO NOT DRILL ADDITIONAL
HOLES IN THE RADOME BASE.
5. If hardware is found in the recessed areas of the radome base try to ascertain where it may have
fallen off From. Notify your dealer immediately.
6.4.2.
Conduct a good, thorough, visual inspection of the antenna pedestal.
Monthly Pedestal Visual Inspection
1. Inspect the AC power conductors inside the breaker box, from the breaker box to the power ring
and from the power ring to the AC power terminal strip.
CAUTION: Assure that ships AC power being supplied to that antenna is
turned OFF prior to touching any AC Power wiring. Hazardous voltages exist
on these wires.
a. Inspect ground wire for damage & proper termination.
b. Assure that the conductors are flexible and that the insulation is not chaffed, brittle or burned. If
any damage is found repair or replace the damaged conductors. If damage is due to chaffing, pinching
or crushing reroute the new conductors as necessary to prevent future damage.
