AP-2330-32

The AP-2330-32 is a strategic-grade terrestrial microwave antenna designed for the 2305–2360 MHz WCS (Wireless Communications Service) band. Featuring a large 2.4-meter (8-foot) grid parabolic reflector, it delivers an elite 32 dBi gain. This antenna is engineered for high-capacity, long-distance point-to-point digital and analogue links, offering exceptional beam precision and structural resilience for tactical and fixed-site infrastructure.

Precision Microwave Performance

The AP-2330-32 is a powerhouse of directional accuracy, featuring a razor-sharp 3.7-degree beam-width. This ultra-narrow aperture concentrates RF energy with clinical precision, maximizing link distance while effectively eliminating interference from adjacent signal sources. Performance is further stabilized by a 40 dB Front-to-Back ratio and 36 dB cross-polarization discrimination, ensuring the high signal-to-noise ratio (SNR) required for sophisticated digital modulation. The use of a brass dipole feed with an air-cored transmission line ensures negligible internal loss.

Advanced Structural Hardening

Constructed from 6063T6 architectural-grade anodized aluminum alloy, the 2.4-meter reflector is designed for survival in the most punishing theaters. 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. To maintain structural alignment in extreme conditions, the antenna is supplied with two side struts for enhanced rigidity. All fasteners are Type 316 marine-grade stainless steel, preventing galvanic corrosion in high-salinity coastal areas.

Operational and tactical Efficiency

Despite its strategic size, the AP-2330-32 is built for professional field optimization. It includes an elevation tracking mechanism allowing for fine +/- 10 degree adjustments, essential for "dialing in" peak signal strength on long-distance hops. 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 an immutable discharge path for lightning and atmospheric static.

Detailed Technical Features

• Exceptional Link Margin: Delivers a mid-band gain of 32 dBi. This high gain allows for the establishment of "backbone" long-distance terrestrial links, effectively bridging gaps between remote sites where standard antennas cannot maintain a reliable connection.
• Ultra-Narrow Focus: Features a razor-sharp 3.7-degree beam-width at half-power points. This clinical precision maximizes link security and provides high immunity to interference from adjacent signal sources.
• Advanced Signal Isolation: * Front-to-Back Ratio: 40 dB, ensuring the antenna is nearly blind to noise and signals originating from behind the station.
  • Cross-Polarized Discrimination: 36 dB, critical for maintaining the high signal-to-noise ratio (SNR) required for sophisticated 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 to ensure maximum 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, shielding the system from atmospheric static and lightning-induced transients.

Detailed Mechanical Features

• Reflector Architecture: The 2.4-meter (8-foot) diameter grid reflector is constructed from 6063T6 architectural-grade anodized aluminum alloy. The open grid design (12.7 mm members) drastically reduces the "sail effect" and torque on the tower compared to solid dishes.
• Precision Tracking & Alignment:
  • Elevation Tracking: Integrated mechanism allowing for fine +/- 10 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.
• Strategic Hardening:
  • Dual Side Struts: Supplied with two support arms to provide extra rigidity to the assembly, ensuring the beam stays on-target during high-wind events.
  • 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.
• Heavy-Duty Mounting: Designed for large-diameter vertical masts up to 110 mm (4 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.
• 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 decades of 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-2330-32 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 (36 dB) to prevent interference between vertical and horizontal channels.
• Pattern Envelope: Meets the required Front-to-Back ratio (40 dB) and beam-width specifications, ensuring spectral efficiency and preventing unwanted signal radiation into adjacent regions.

Technical Summary Comparison

The AP-2330-32 is a strategic communication asset designed to provide the ultimate high-gain, terrestrial link across the 2.3 GHz spectrum. By utilizing a massive 2.4-meter aperture and precision grid engineering, it offers a definitive advantage for long-distance backbone communication where standard antennas cannot maintain a stable digital link.

Key Advantages

• Elite Link Margin: The primary advantage is its massive 32 dBi gain. This provides the necessary power to establish ultra-long-distance point-to-point hops, effectively bridging gaps between remote tactical sites or regional infrastructure hubs.
• Razor-Sharp Directivity: With a 3.7-degree beam-width, the antenna focuses RF energy with clinical precision. This not only maximizes signal reach but also ensures the link is inherently secure and highly resistant to interception or interference from adjacent signals.
• Superior Signal Isolation: Featuring a 40 dB Front-to-Back ratio, the AP-2330-32 is nearly "blind" to noise and signals originating from behind the station. Combined with 36 dB cross-polarized discrimination, it provides the high signal-to-noise ratio (SNR) required for sophisticated 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 an 8-foot dish to be safely mounted in environments where a solid dish would be structurally impossible.
• Dynamic Alignment: The integrated elevation tracking mechanism (+/- 10 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 refraction can impact signal alignment.

Strategic Benefits

• Infrastructure Optimization: By enabling longer-distance hops with higher stability, the AP-2330-32 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 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.
• Structural Reliability: The inclusion of dual side struts as standard equipment ensures the antenna maintains its precise alignment and parabolic shape even during high-vibration or severe weather events.
