The Folded Dipole Collinear Antenna covering the 403–520 MHz frequency range is a robust, wideband omnidirectional antenna designed for reliable VHF/UHF communication systems. Utilizing a folded dipole radiating element arranged in a collinear configuration, this antenna delivers a consistent 3 dBi gain, providing improved signal strength and uniform coverage compared to a standard half-wave dipole.
Engineered for wideband performance, the antenna maintains stable impedance and low VSWR across the entire operating band, ensuring efficient power transfer and reduced signal loss. The folded dipole design offers enhanced bandwidth, better radiation efficiency, and improved matching, making it suitable for multi-channel and frequency-agile radio systems.
With an omnidirectional radiation pattern in the horizontal plane, the antenna provides even 360-degree coverage, making it ideal for base stations, repeaters, telemetry systems, and professional wireless communication networks. The vertically polarized pattern supports consistent mobile and fixed-station communication.
Constructed using high-quality conductive materials and housed in a durable, weather-resistant enclosure, the antenna is suitable for indoor or outdoor installation. Its rugged design ensures long-term reliability under varying environmental conditions such as heat, humidity, wind, and rain. The antenna is typically supplied with a standard RF connector and is compatible with commonly used coaxial cables.
The Folded Dipole Collinear Antenna 403–520 MHz, 3 dBi is an excellent choice for applications requiring wide frequency coverage, stable performance, moderate gain, and dependable omnidirectional radiation, including public safety communications, industrial radio systems, SCADA, telemetry, and wireless data links.
