Zero Maintenance Needs​​ Passive antennas sidestep nearly all maintenance headaches because they contain no electronics or moving parts. Unlike active antennas – which require quarterly voltage checks, cooling system inspections, and component replacements – a passive unit just sits there doing its job year after year. Materials like hardened fiberglass radomes and marine-grade aluminum housings […]

When designing or selecting an antenna, tracking six key parameters ensures optimal performance. The gain, typically ranging from 3 dBi to 20 dBi, determines directional efficiency, while the frequency range (e.g., 2.4 GHz–5 GHz for Wi-Fi) must match the application. VSWR (Voltage Standing Wave Ratio) below 2:1 indicates good impedance matching, minimizing signal loss. Radiation
