Maintainance & Inspection

National Microwave provides inspection, testing, and repair to all items related to existing tower site structures. We have the proper test equipment and tools for testing and repairing tower problems using such equipment as Anritsu Site Master, Anritsu spectrum analyzer, or Anritsu Scalar Network Analyzer.

Site Inspection Report (with pictures) shall be prepared on each site documenting:
•    Antennas: antenna azimuth, downtilts, model numbers by face.
•    Tower: tower type, condition, location, grounding, alignment, cabling, platform, etc.
•    Shelter/Cabinet: type, condition, etc.
•    Compound: condition, etc.
•    Grounding: test results.

Items covered include, but are not limited to, the following:
1) Grounding System
2) Antennas
3) Connectors
4) Jumpers
5) Coax & Waveguide
6) Array Platform
7) Tower Structure
8) Lighting

Inspection of paint integrity and compliance with FAA regulations.
