COALAS::STRYJEN-480-520 antenna from Coalas systems — a vertical dipole combining compact size and reliable performance in the 480 MHz–520 MHz frequency range. This model is designed for stable signal reception and transmission in industrial and commercial applications, telemetry, radio communications, and other systems requiring correct operation in the specified sub-band.

Description and Purpose

The COALAS::STRYJEN.480-520 vertical dipole is optimized for operation in the 480–520 MHz band with a resonant frequency of 500 MHz. With a bandwidth of 40 MHz at VSWR < 1.5, the antenna ensures high-quality reception and transmission without significant VSWR degradation across the entire sub-band. The dipole design guarantees compatibility with common radio modems and radio transmitters for this frequency, providing stable directivity and matching.

Key Features

• Frequency range: 480 MHz – 520 MHz
• Resonant frequency: 500 MHz
• Bandwidth: 40 MHz (VSWR < 1.5)
• Gain: 2 dBi
• Antenna type: vertical dipole
• Connector: IPEX Female + RG178 cable (400 mm)
• Dimensions: 330 mm x 15 mm
• Weight (without mounting): 80 g

Compact dimensions (330 mm length, 15 mm diameter) and a weight of 80 g make the antenna convenient for mounting in confined spaces — on both portable and stationary devices. The presence of an IPEX Female connector and a short RG178 cable (400 mm) facilitates connection to modules equipped with micro-connectors, or via adapters to other connector types.

COALAS::STRYJEN-480-520 is designed with practical requirements in mind: it provides a stable signal in the operating range, has a bandwidth margin for frequency deviations in communication channels, and is suitable for systems where reliability and compactness of the antenna element are important. Typical applications include industrial and commercial projects, telemetry systems, data transmission networks, and devices with limited space for antenna mounting.

Operating Recommendations

• Install the antenna vertically to achieve optimal dipole characteristics.
• Avoid placement near large metal objects that may affect VSWR and directivity.
• If necessary, use adapters to convert IPEX to other connector types according to your equipment's needs.

Technical compatibility and mobility make COALAS::STRYJEN-480-520 an attractive solution for integration into various systems requiring high-quality operation in the 480–520 MHz range. Product type: Antennas > Dipole antennas.
