AP-2330-29

The AP-2330-29 is a high-gain terrestrial microwave antenna designed for the 2305–2360 MHz WCS band. Featuring a 1.8-meter (6-foot) grid parabolic reflector, it delivers a strategic 29 dBi gain. This antenna is optimized for long-distance point-to-point digital and analogue links, offering a narrow beam-width and high structural resilience for tactical and fixed-site communication infrastructure.

Precision Microwave Performance

The AP-2330-29 offers exceptional directional accuracy with a sharp 4.9-degree beam-width. This focused aperture concentrates RF energy precisely on the target receiver, maximizing link distance while minimizing interference from adjacent signals. Performance is further enhanced by a 37 dB Front-to-Back ratio and 34 dB cross-polarization discrimination, ensuring the high signal-to-noise ratio (SNR) required for high-capacity digital backhaul.

Advanced Structural Hardening

Constructed from 6063T6 architectural-grade anodized aluminum alloy, the 1.8-meter reflector is built for survival in punishing environments. The grid architecture is a critical efficiency feature; the open-frame design allows wind to pass through the reflector, drastically reducing wind load compared to solid dishes and achieving a wind rating of 200 Km/Hr. All fasteners are Type 316 marine-grade stainless steel, preventing galvanic corrosion in high-salinity coastal areas.

Operational and Tactical Efficiency

Designed for professional field optimization, the AP-2330-29 includes an elevation tracking mechanism allowing for fine +/- 8 degree adjustments to "dial in" peak signal strength. The primary feed horn features a quick fastener system for rapid assembly, and the sensitive radiating elements are completely sealed inside an ABS radome for all-weather protection. For electrical safety, the antenna operates at direct D.C. ground, providing a safe discharge path for lightning and atmospheric static.

Detailed Technical Features

• Strategic Link Margin: Delivers a mid-band gain of 29 dBi. This provides the necessary power to establish long-distance terrestrial links, bridging gaps between remote sites where standard antennas cannot maintain a stable connection.
• Precision Beam Control: Features a sharp 4.9-degree beam-width at half-power points. This narrow aperture maximizes link security and provides high immunity to interference from adjacent signal sources.
• Advanced Signal Isolation:
  • Front-to-Back Ratio: 37 dB, ensuring the antenna effectively ignores noise and signals originating from behind the station.
  • Cross-Polarized Discrimination: 34 dB, critical for maintaining the high signal-to-noise ratio (SNR) required for high-capacity digital modulation.
• High-Efficiency Feed System: The antenna dipole feed uses an Air-Cored transmission line with a primary feed horn. Radiating elements are made of high-quality brass for maximum electrical conductivity and negligible internal loss.
• Stable Impedance: Maintains a VSWR of better than 1.3:1 across the entire bandwidth, ensuring optimal power transfer and protecting connected radio equipment.
• Lightning Protection: Operates at direct D.C. ground with a low-resistance discharge path to protect the system from atmospheric static and lightning transients.

Detailed Mechanical Features

• Reflector Architecture: The 1.8-meter (6-foot) diameter grid reflector is constructed from 6063T6 architectural-grade anodized aluminum alloy. The open grid design (12.7 mm members) reduces the "sail effect" and torque on the tower compared to solid dishes.
• Precision Alignment Tracking:
  • Elevation Tracking: Integrated mechanism allowing for fine +/- 8 degree adjustments. This is essential for "dialing in" peak signal strength on long-distance hops after the antenna is mounted.
  • Versatile Polarization: The mounting arrangement permits a 90-degree rotation to switch between Horizontal and Vertical polarization in the field.
• Industrial Hardening:
  • Marine-Grade Hardware: All screws, nuts, and bolts are manufactured from Type 316 Stainless Steel to prevent galvanic corrosion.
  • Protected Feed: The sensitive dipole feed is completely sealed inside a high-impact ABS radome for all-weather protection.
  • Quick Fastener System: The primary feed horn is fitted to the center of assembly with a quick fastener system for rapid field setup.
• Mounting Interface: Clamps securely to vertical masts with a diameter up to 76 mm (3 inches).

Detailed Environmental Features

• Hurricane Resilience: The grid design allows for a wind rating of 200 Km/Hr (125 MPH). The open-frame architecture significantly lowers the structural demand on masts in storm-prone regions.
• Extreme Thermal Window: Operational in temperature ranges from -30°C to +70°C and storage-rated from -40°C to +80°C.
• Corrosive Theater Protection: The combination of anodized aluminum, stainless steel hardware, and an anti-corrosive Army Green powder coating ensures a long service life in coastal and tropical climates.
• High Humidity Tolerance: Certified for operation in 0 to 95% RH environments without performance drift or internal oxidation.

FCC Compliance

The AP-2330-29 is engineered to meet the highest regulatory standards for directional microwave equipment:

• Standard: 100% in compliance with FCC Part 101.115.
• Cross-Polarization Discrimination: Strictly adheres to mandated isolation levels (34 dB) to prevent interference between vertical and horizontal channels.
• Pattern Envelope: Meets the required Front-to-Back ratio (37 dB) and beam-width specifications, ensuring spectral efficiency and preventing unwanted signal radiation into adjacent regions.

Technical Summary Comparison

Key Advantages

• Strategic Link Margin: The primary advantage is its 29 dBi gain. This provides the necessary power to establish long-distance point-to-point hops, effectively bridging gaps between remote tactical sites or regional infrastructure hubs.
• Precision Directivity: With a 4.9-degree beam-width, the antenna focuses RF energy with clinical accuracy. This not only maximizes signal reach but also ensures the link is inherently secure and highly resistant to interference from adjacent signals.
• Superior Signal Isolation: Featuring a 37 dB Front-to-Back ratio, the AP-2330-29 is effectively "blind" to noise and signals originating from behind the station. Combined with 34 dB cross-polarized discrimination, it provides the high signal-to-noise ratio (SNR) required for high-capacity digital data streams.
• Low Wind Loading: Unlike solid parabolic dishes of this size, the grid architecture allows wind to pass through the reflector. This significantly reduces the "sail effect" and torque on the tower, allowing a 6-foot dish to be safely mounted in environments where a solid dish would be structurally risky.
• Dynamic Alignment: The integrated elevation tracking mechanism (+/- 8 degrees) allows for extensive fine-tuning after the antenna is mounted. This is critical for optimizing links across uneven terrain or across long distances where atmospheric conditions may impact signal alignment.

Strategic Benefits

• Infrastructure Optimization: By enabling longer-distance hops with high stability, the AP-2330-29 can reduce the total number of relay towers required for a cross-country link, lowering both capital and maintenance expenditures.
• Professional Regulatory Compliance: Being 100% FCC Part 101.115 compliant, this antenna meets the strict standards required for high-capacity directional communication in the United States and other strictly regulated international markets.
• Theater-Hardened Resilience: Constructed from anodized 6063T6 aluminum with 316 stainless steel fasteners, the antenna is immune to salt fog and high humidity. The ABS-enclosed feed ensures that sensitive radiating elements never come into contact with corrosive environmental factors.
• Tactical Mobility: At a gross weight of 35 Kgs, it offers a superior balance of high gain and portability, allowing for rapid deployment by a two-person team using quick-fastener systems.
