Kružna antena Qoltec 57014

The Qoltec 57014 omni-directional antenna delivers broad-area signal coverage across a wide frequency range of 0.6–2.7 GHz. Designed with vertical polarization and a durable ABS housing in white, this antenna offers a high maximum gain of 30 dBi while maintaining a 50 Ω impedance for compatibility with common RF equipment. At 356 g, it provides a balance of robust construction and manageable weight for indoor and outdoor mounting scenarios where stable, omnidirectional reception or transmission is required.

Advantages

The antenna provides high gain performance up to 30 dBi within a wide frequency band, enabling improved signal strength and extended range for compatible devices. Its vertical polarization supports standard vertically polarized systems, while the 50 Ω impedance ensures straightforward integration with most RF systems and cabling. The ABS housing offers physical durability and environmental resistance, and the antenna's relatively low weight simplifies installation and mounting.

Suitable for

• Extending coverage for Wi‑Fi access points and repeaters operating within 0.6–2.7 GHz
• Wireless data links and telemetry where omni-directional coverage is required
• Systems requiring a vertically polarized antenna with a 50 Ω interface
• Indoor and sheltered outdoor installations that benefit from a lightweight antenna

How to use

Mount the antenna in a location that provides clear line-of-sight where possible and minimal obstructions for optimal omnidirectional coverage. Connect the antenna to RF equipment using compatible 50 Ω cabling and appropriate connectors; ensure connectors are tightened and, for outdoor applications, sealed against moisture. Position the antenna vertically to match its polarization and adjust placement height to improve area coverage. Verify system settings and perform signal measurements to confirm expected gain and coverage improvements.

Recommendations

For best results, use the Qoltec 57014 with equipment specified for 50 Ω impedance and maintain vertical orientation. Avoid placing the antenna near large metallic structures or dense foliage that can attenuate signals. For outdoor installations, use weatherproof connectors and mounting hardware compatible with ABS housing to prevent mechanical stress and water ingress.
