D2118 Dipole Antenna
The D2118 Dipole Antenna is a rugged, multi-element VHF/UHF dipole supporting simultaneous communications across the 116–150 MHz and 225–400 MHz bands. Engineered for defense and aviation applications, it delivers reliable omni-directional coverage in a compact form.
Description
The D2118 Dipole Antenna is a high-performance and designed for simultaneous VHF and UHF operation within a single radome. With three internal elements and three independent RF connectors, it supports concurrent communication over the 116–150 MHz and 225–400 MHz frequency bands, ideal for mission-critical military and aviation systems. The antenna provides stable 2 dBi omni-directional gain with vertical polarization and is enclosed in a durable fiberglass radome. Built to withstand challenging environmental conditions, the D2118 ensures dependable connectivity.
