Scale Dense PtMP NetworksCyber Antennas’ Double 20° Asymmetrical Horn 4x4 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 20-30° 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 Double 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 Double A20 helps WISPs push more capacity through limited spectrum, even on noisy, congested sites. High-Gain 20-30° Horn Sector for Crowded Towers The Double A20’s narrow 20° to 30° 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° to 30° horns, operators can reduce self-interference, raise SINR, and maintain higher MCS levels, translating directly into more usable capacity per AP. The Double 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 Control Because the Double 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 Topologies The Double 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 20-30° 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 Double 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° to 30° sector for both legacy and next-generation deployments. High-Gain Performance from 4.9-7.1 GHz The Double 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 Patterns Many “high-gain” antennas achieve their gain by trading off pattern quality or by being heavily optimized for a narrow slice of spectrum. The Double 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 Deployments Because the Double 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 Alternatives The Double 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° to 30° beam with industry-leading wideband performance, the Double A20 gives operators a powerful lever for increasing per-sector capacity without adding spectrum. Ready for 5 GHz Today and 6 GHz Tomorrow With full coverage of both the traditional 5 GHz band and the newer 6 GHz allocations, the DOUBLE-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 Double 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° to 30° 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 Double 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 Towers The Double 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 Cambium ePMP 3000, ePMP 4600, or Mimosa A5c, 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 Double A20 sectors in tight vertical and horizontal spacing. Cambium Networks ePMP 3000 Cambium positions the ePMP 3000 as its flagship 802.11ac Wave 2 PtMP access point, claiming up to 1.2 Gbps of sector capacity while serving 120+ subscribers. It uses 4x4 MU-MIMO with dual overlapping sectors so it can transmit to two subscriber modules at the same time, which Cambium says effectively doubles the capacity vs. 2x2 systems and improves link budget by ~3 dB via downlink beamsteering. Cambium also highlights optional smart uplink beamsteering for extra uplink isolation, dynamic filtering to mitigate neighboring-channel interference, and TDD synchronization to scale dense networks to thousands of end users while reusing a small number of channels. Cambium notes the ePMP 3000 can be deployed with broader 90° sectors or a 60° MU-MIMO horn, but in crowded towers and high-noise sites, the fastest way to unlock the radio’s MU-MIMO/beamsteering advantages is to tighten the RF footprint. The Cyber Antennas A20 (20° asymmetrical horn) delivers a much narrower beamwidth than 60°/90° options, which improves sector isolation, reduces self-interference, and enables more aggressive frequency reuse—helping the ePMP 3000 sustain higher SINR and higher MCS for more real capacity per tower. Designed to Solve Common WISP ChallengesRF Interference in Congested Environments The DOUBLE-A20's narrow 20° 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 sector performance. Excessive Sector Overlap Wide sector antennas can create significant overlap and self-interference, especially on crowded tower sites. The DOUBLE-A20 provides tightly controlled 20° coverage, allowing operators to target specific service areas with greater precision. Limited Network Capacity As subscriber density increases, wide sectors can become overloaded and reduce available airtime per user. The DOUBLE-A20 enables operators to divide coverage into multiple narrow sectors, increasing frequency reuse and improving capacity in high-demand areas. Inefficient Spectrum Utilization In crowded RF environments, efficient spectrum use is critical. The DOUBLE-A20's focused radiation pattern minimizes unwanted RF energy outside the intended coverage area, allowing operators to reuse channels more effectively and maximize available spectrum.

Operators can upgrade to Wi-Fi 6E and Wi-Fi 7 technologies without replacing antennas, protecting existing infrastructure investments. Targeted Coverage Requirements Some deployments require focused coverage in a specific direction, such as neighborhoods, apartment complexes, business parks, or industrial areas. The DOUBLE-A20 concentrates RF energy where it is needed, reducing wasted coverage and improving network efficiency. Scalability on Existing Tower Sites As network demand grows, operators often need to increase capacity without building new towers. The DOUBLE-A20 makes it easier to deploy additional narrow sectors on existing infrastructure, helping expand network capacity while minimizing deployment costs. Typical Use CasesHigh-Density PtMP Sectors Deploy narrow 20° sectors to serve concentrated groups of subscribers while maintaining high SINR and maximizing sector capacity. Crowded Tower Sites Reduce sector overlap and self-interference when multiple APs are co-located on the same tower. Aggressive Frequency Reuse Reuse channels more effectively around a tower or across nearby sites by creating tightly controlled coverage footprints. Spot-Beam Coverage Target neighborhoods, apartment complexes, business parks, industrial areas, or other dense subscriber clusters that require additional capacity. 6 GHz Network Overlays Add high-performance 6 GHz sectors alongside existing 5 GHz infrastructure to increase capacity without rebuilding the entire site. Wi-Fi 7 and Multi-Gigabit PtMP Deployments Pair with modern 4x4 MIMO radios to deliver multi-gigabit services with higher throughput and improved spectrum efficiency. Corridor and Linear Coverage Provide focused coverage along roads, valleys, rail lines, shorelines, or other long, narrow service areas where wide sectors would waste RF energy.
