5. MAINTENANCE 

5.1.  Maintenance Overview 

After installation, the antenna requires only periodic inspection.  It is anticipated that 

maintenance, if required, will be minimal and easily handled by a local or in-house 

maintenance staff.  

 

5.2.  Periodic Inspection 

It is suggested that a periodic inspection be performed at least every six months. 

 

NOTE:  After any very severe weather conditions, inspection of the antenna should be performed to 

determine if foreign objects have caused damage or if survival specifications have been exceeded. 

 

This inspection should include the following: 

1) Check all bolting locations - all bolts should be tight. 

2) Check all structural members - repair or replace if damaged. 

3) Check the foundation anchor bolts - they must be secure and with no failure signs in foundation. 

4) Check for corrosion - on the reflector structure and mount. 

5.3.  Reflector 

General Dynamics' reflector does not require any maintenance.  The composite construction of the 

reflector  is  virtually  impervious  to  any  damages  that  could  be  caused  by  weather  or  other 

atmospheric conditions.  It is only necessary to inspect for any physical damage done by vandalism 

or very severe weather conditions.  Should any damage be detected to a portion of the reflector, 

contact  the  Customer  Service  Department  at  General  Dynamics  for  recommendations  involving 

reflector repair. 

5.4.  Mount and Reflector Support Structure 

The mount  and  reflector  support  structure  supplied  with  this  antenna  is  of  steel  construction  and 

has a hot-dipped galvanized finish.  If inspection shows any signs of structural failure, the mount 

members that are damaged should be repaired or replaced. 

Corrosion:  Any corrosion on steel members may be repaired with a zinc-rich cold galvanizing paint. 

5.5.  Repair and / or Replacement 

Any  questions  or  issues  regarding  repair  or  replacement  parts  should  be  addressed  to  General 

Dynamics’s customer service department at:
