SA UHF83 Dipole Antenna

SA UHF83 Marine & Base Station Antenna

Scan Antenna UHF83 Dipole Antenna is a premium, high-gain fiberglass antenna specifically designed for the maritime environment and land-based radio systems. Built by Scan Antenna, it is renowned for its durability and consistent performance in the UHF frequency range (380 – 510 MHz).

Features

• High Gain Performance: Delivers a 3 dBd (5.1 dBi) gain, significantly extending your communication range compared to standard antennas.

• Heavy-Duty Construction: Features a high-quality fiberglass tube and chrome-plated solid brass fittings to withstand salt spray and extreme weather.

• Wide Bandwidth: Available in multiple sub-bands to ensure a perfect VSWR (Voltage Standing Wave Ratio) match for your specific frequency needs.

• No Ground Plane Required: Designed as a half-wave dipole, meaning it does not require a metal ground plane for optimal performance.

Specifications

Mechanical Environmental

• Materials: White polyurethane-coated fiberglass, chrome-plated brass.
