When selecting a 5G telecom antenna, consider: (1) Frequency band (sub-6GHz or mmWave like 28/39GHz), (2) Gain (8-15dBi for urban, up to 24dBi for rural), (3) Beamwidth (30°-65° for sector coverage), (4) MIMO support (4×4 or 8×8 arrays), (5) IP rating (IP65+ for outdoor durability), (6) Power handling (50W+ for macro cells), and (7) Regulatory […]

Antenna dish gain measures signal amplification relative to an isotropic radiator. To calculate: (1) Determine dish diameter (D) and signal wavelength (λ), (2) Compute efficiency (η, typically 55-75%), (3) Apply formula G = η×(πD/λ)², (4) Convert to decibels: dBi = 10log₁₀(G). A 2.4m dish at 12GHz with 60% efficiency yields ~40dBi gain. Manufacturing imperfections may
