Document any discrepancies immediately and contact Advanced Microwave Technologies' technical support team before proceeding with the installation to avoid complications or performance issues.

Assembly and Alignment Procedures

The assembly of a Feed Fired Lens Antenna requires methodical attention to detail, as proper alignment directly impacts performance. Begin by assembling the mounting structure according to the provided diagrams, ensuring all load-bearing components are secure before attaching any antenna elements. When mounting the lens component, use the specified torque values for all fasteners to prevent warping of the precision-manufactured surfaces. The critical aspect of assembly is the relationship between the feed and the lens—this distance and alignment must be precisely set according to the specifications provided by Advanced Microwave Technologies for your specific model. Using alignment jigs or laser measurement tools can help achieve the required precision. For models with adjustable feed positions, carefully follow the calibration instructions to achieve the desired beamwidth characteristics. The feed must be centered relative to the lens with angular alignment within fractions of a degree to prevent beam distortion. During assembly, protect the connector interfaces from contamination, as even microscopic particles can create signal reflection points. For antennas with circular polarization options, verify the orientation of polarization elements according to the system requirements. Once the physical assembly is complete, perform preliminary electrical continuity tests before connecting to RF sources. Advanced Microwave's Feed Fired Lens Antennas often incorporate precision alignment markers or reference points to facilitate this process. For larger models with high gain specifications (approaching 45 dBi), the alignment process may require specialized equipment to verify far-field pattern characteristics. Document all alignment settings and torque values applied during assembly for future reference during maintenance procedures.

Cable Management and Weatherproofing Techniques

Proper cable management and weatherproofing are essential for maintaining the performance and longevity of your Feed Fired Lens Antenna system. Begin by planning cable routes to minimize bend radii that could degrade signal quality, especially for high-frequency operations approaching the upper limit of the 40 GHz capability. All connection points must be weatherproofed using appropriate methods for your environment—typically involving multiple layers of protection. Start with proper connector cleaning and mating, ensuring connectors are tightened to manufacturer specifications. Apply self-amalgamating silicone tape as the primary moisture barrier, followed by UV-resistant electrical tape, ensuring each layer overlaps adequately and creating a downward-shedding pattern to prevent water ingress. For extreme environments, additional weatherproofing boots or enclosures may be necessary. Cable strain relief is critical, as movement from wind loads can cause connector fatigue over time. Install proper cable supports at intervals determined by the cable type and environmental conditions, ensuring supports don't deform cables beyond their minimum bend radius. Ground all components according to both manufacturer specifications and local electrical codes to protect against lightning strikes and static discharge. Advanced Microwave Technologies' Feed Fired Lens Antennas incorporate specialized weatherproofing features for critical components, but field connections require careful attention. For locations with extreme temperature variations, allow sufficient slack in cables to accommodate thermal expansion and contraction while maintaining proper support. Document weatherproofing procedures performed for each connection point to facilitate future maintenance inspections and ensure consistency in protection methods throughout the installation.
