​​Selecting a high-gain antenna requires evaluating four key factors: frequency range (e.g., 2.4GHz or 5GHz for Wi-Fi), gain rating (15-20dBi for long-range), radiation pattern (omnidirectional vs directional), and impedance matching (50Ω standard). For optimal performance, ensure proper alignment (within ±5° of target) and elevation (minimum 3m clearance). Outdoor models should have IP65+ waterproofing, while grid/parabolic […]

High gain horn antennas excel in performance with key metrics: gain (15-25 dBi), frequency range (1-40 GHz), and VSWR (<1.5:1). They achieve 90% radiation efficiency and 30 dB front-to-back ratio, minimizing sidelobes. Beamwidth narrows to 10°–30°, enhancing directivity. To optimize, align the feed precisely (λ/4 offset), use smooth waveguide transitions, and ensure impedance matching (50Ω).
