Omni Antenna 300 - 500 MHz

Deliver dependable wideband coverage with our 503-7A03B Omni Antenna, purpose-built for 300–500 MHz professional radio systems. A low ≤1.2 VSWR and 50 Ω impedance drive RF efficiency, while 2 dBi omnidirectional gain with 360° horizontal coverage ensures uniform signal distribution. Vertical polarization and a 55–110° vertical beamwidth support stable links in dense environments. Rated to 50 W, the compact, lightweight form factor (Φ185 × 85 mm, 0.2 kg) integrates easily via N‑female bottom feed. Operating from −40 to +65 °C, it’s ideal for LMR/public safety, UHF telemetry, SCADA, repeaters, and DAS nodes seeking reliable, consistent in‑band performance.
