When comparing antenna ranges, key factors include transmit power (typically 1-100W affecting range exponentially), gain (6dB increase doubles range), frequency (lower frequencies like 900MHz propagate farther than 2.4GHz), and environmental conditions (urban areas may reduce range by 50-70% versus open terrain). Receiver sensitivity (-110dBm to -80dBm) and antenna height (optimal 5-30m elevation) also critically influence […]

The five key antenna performance parameters are gain (typically 3-15 dBi for directional antennas), bandwidth (e.g., 2.4-2.5 GHz for WiFi), radiation pattern (main lobe beamwidth of 30°-120°), impedance (standard 50Ω matching with <1.5:1 VSWR), and efficiency (60-90% for well-designed antennas). Polarization (linear/circular with axial ratio <3dB) also critically impacts performance, especially in multipath environments at
