Scale Dense PtMP NetworksCyber Antennas’ 20° Asymmetrical Horn (A20) gives WISPs a high-gain, tightly focused sector specifically tuned for scaling dense, high-capacity PtMP networks across the 5 GHz and 6 GHz unlicensed bands. Its narrow 20° beam delivers clean, controlled coverage that keeps signal where it is needed and out of where it isn’t, enabling aggressive frequency reuse, higher modulation rates, and more subscribers per tower. With wideband 4.9–7.1 GHz operation, operators can standardize on the A20 for both 5 GHz and 6 GHz deployments, simplifying planning, procurement, and spares while unlocking additional spectrum for growth. Designed as a PtMP sector rather than a general-purpose PtP bridge, the A20 helps WISPs push more capacity through limited spectrum, even on noisy, congested sites.
High-Gain 20° Horn Sector for Crowded TowersThe A20’s narrow 20° asymmetrical beam allows WISPs to break a site into tightly defined coverage slices, dramatically improving sector isolation on crowded towers. By replacing wide, overlapping sectors with focused 20° horns, operators can reduce self-interference, raise SINR, and maintain higher MCS levels, translating directly into more usable capacity per AP. The A20’s high gain and clean radiation pattern help ensure that energy is concentrated into the intended service area instead of spilling into adjacent sectors or off-site, which is critical when every dB of signal quality matters.
Aggressive Frequency Reuse and Interference ControlBecause the A20 has a sharply controlled main lobe and suppressed sidelobes, WISPs can reuse the same channels more aggressively around a tower or across nearby sites. The clean pattern limits unintended overlap between sectors, making it easier to design frequency plans that avoid destructive interference while still maximizing total throughput. This tight control of RF energy is especially valuable in noisy environments, where reducing off-axis noise pickup and self-interference often yields more capacity than simply adding more spectrum.
Optimized Coverage for Real-World WISP TopologiesThe A20 is engineered to match how WISPs actually build networks: from ridge lines and hillsides down into valleys, along roads and rail corridors, and across mixed-density neighborhoods, business parks, and industrial zones. Its 20° beam can be used to surgically target long, narrow coverage areas or specific noisy directions that require extra gain and isolation. This lets operators align RF footprints with the physical layout of the homes and businesses they serve, rather than forcing coverage into generic wide-beam shapes that waste signal outside the target zone.
Industry-leading 5 GHz and 6 GHz Wideband PerformanceThe Cyber Antennas 20° Asymmetrical Horn (A20) is engineered as a true wideband 5 GHz and 6 GHz sector, delivering consistent, high realized gain and clean radiation patterns from 4.9–7.1 GHz. Instead of having a narrow “sweet spot” like many band-specific designs, the A20 maintains strong performance across the entire band, enabling WISPs to move freely between 5 GHz and 6 GHz channels without sacrificing throughput or signal quality. This wideband capability not only improves real-world subscriber speeds but also simplifies network design, frequency planning, and inventory management, allowing operators to standardize on a single high-gain 20° sector for both legacy and next-generation deployments.
High-Gain Performance from 4.9–7.1 GHzThe A20 is carefully tuned to provide consistently high realized gain and efficient signal power transfer across its full 4.9–7.1 GHz operating range. Rather than peaking in a narrow portion of the band, the antenna’s response is optimized so that link budgets and modulation rates remain strong whether you’re running traditional 5 GHz channels or opening up new capacity in 6 GHz. This smooth, predictable performance allows WISPs to design and scale networks without worrying that moving to a different channel or band will compromise signal strength or coverage.
Clean Radiation PatternsMany “high-gain” antennas achieve their gain by trading off pattern quality or by being heavily optimized for a narrow slice of spectrum. The A20’s wideband horn design delivers both: strong gain and a clean, controlled pattern with suppressed sidelobes across the entire supported band. This means WISPs get reliable beam shape, isolation, and interference control whether operating in 4.9 GHz, 5 GHz, or 6 GHz, avoiding the pattern distortions and performance drops that can occur when narrowband antennas are used outside their ideal frequency window.
Simplified Procurement and Standardized DeploymentsBecause the A20 covers 4.9–7.1 GHz with a single design, operators can standardize on one 20° sector model instead of juggling separate SKUs for different parts of the band. This simplifies procurement, spare management, and tower planning: the same horn can be used for 5 GHz today and 6 GHz expansion tomorrow, without changing antenna hardware. The result is less complexity in the field, fewer configuration surprises, and easier scaling as new spectrum becomes available or frequencies need to be shuffled to manage noise.
Higher Throughput Than Band-Specific AlternativesThe A20’s wideband efficiency and optimized horn geometry have been tested to deliver more efficient signal power transfer and higher realized gain from 4.9–7.1 GHz than comparable narrowband horn sectors within their respective frequency slices. In real-world WISP deployments, this translates into higher MCS levels, stronger downlink budgets, and more than 15% improvement in subscriber download speeds compared to many similar narrowband 20–30° horn sectors. By combining a tight 20° beam with industry-leading wideband performance, the A20 gives operators a powerful lever for increasing per-sector capacity without adding spectrum.
Ready for 5 GHz Today and 6 GHz TomorrowWith full coverage of both the traditional 5 GHz band and the newer 6 GHz allocations, the A20 is ready for current and next-generation radio platforms, including Wi-Fi 6E and Wi-Fi 7 MLO-based PtMP systems. WISPs can deploy the A20 on existing 5 GHz infrastructure and later migrate sectors or entire sites into 6 GHz as radios and regulatory environments evolve—using the same proven 20° sector antenna. This protects infrastructure investments and ensures that tower work done today continues to pay off as networks transition to higher-capacity 6 GHz channels.
Radio Compatibility & WISP Deployment ScenariosRadio compatibility is determined by the connector type, frequency range, and intended application.
This antenna has RP-SMA female bulkhead connectors and includes short RF jumper cables for direct connection to the most popular Ubiquiti, Cambium, Mimosa, and MikroTik radios with connectors.
The A20 operates from 4.9-7.1 GHz including the entire 4.9 GHz, 5 GHz, and 6 GHz bands.
It is optimized for PtMP sector coverage and is particularly effective in dense, interference-heavy deployments such as crowded towers, MicroPoPs, urban neighborhoods, where precise coverage and aggressive frequency reuse are critical.
High-Capacity PtMP AP Sectors on Crowded TowersThe A20 excels as a PtMP AP sector on crowded towers where WISPs need to squeeze more capacity out of limited spectrum. Paired with radios like Rocket LTU, ePMP 4600L, or Mimosa A5x, the horn’s tight 20° beam and high gain allow operators to split sites into narrow, high-SINR coverage slices, reducing overlap and self-interference between sectors. This enables more aggressive frequency reuse and higher sustained MCS levels, resulting in more subscribers per AP and higher aggregate throughput per tower. The compact, lightweight form factor and secure mounting hardware also make it easier to deploy multiple A20 sectors in tight vertical and horizontal spacing.
Designed to Solve Common WISP ChallengesRF Interference in Congested Environments
The A20's narrow 20° asymmetrical beamwidth and horn antenna design help reject unwanted signals and reduce interference from neighboring sectors and nearby radios. This improves signal quality, network stability, and overall network performance in dense RF environments.
Excessive Sector Overlap
Traditional wide sector antennas often radiate RF energy into unintended areas, creating overlap and self-interference between sectors. The A20 provides tightly controlled 20° coverage, allowing operators to serve specific areas with greater precision and minimal overshoot.
Limited Network Capacity
When too many subscribers share a broad coverage area, available airtime and throughput can decrease. The A20 enables operators to divide coverage into multiple narrow sectors, increasing frequency reuse and improving capacity on high-density tower sites.
Inefficient Spectrum Utilization
In crowded wireless environments, available channels are a valuable resource. The A20's focused beam pattern minimizes unwanted radiation outside the intended coverage area, allowing operators to reuse frequencies more effectively and maximize spectrum efficiency.
Migration to 6 GHz Networks
With true wideband 4.9–7.1 GHz coverage, the A20 supports both 5 GHz and 6 GHz radios. Operators can adopt Wi-Fi 6E and Wi-Fi 7 technologies without replacing antennas, protecting existing infrastructure investments and simplifying future network upgrades.
Coverage of Long, Narrow Service Areas
Some deployments require coverage in a specific direction, such as along highways, valleys, shorelines, industrial corridors, or concentrated subscriber clusters. The A20's narrow asymmetrical coverage pattern focuses RF energy precisely where it is needed, reducing wasted coverage and improving network efficiency.
Scalability on Existing Tower Sites
As subscriber demand increases, operators often need to add more sectors without building additional towers. The A20's compact 20° coverage pattern makes it easier to deploy more sectors on existing infrastructure, increasing network capacity while minimizing deployment costs.
High-Density Tower Deployments
Co-located radios and antennas on busy tower sites can create RF congestion and limit performance. The A20's excellent beam control and high front-to-back rejection help reduce sector-to-sector interference, making it well suited for high-density multi-sector deployments.
