GL-NL550 144/430MHz Fiberglass Antenna 3.0dB(144MHz)5.5dB(430MHz)

Product Overview

GL-NL550 144/430MHz Fiberglass Antenna 3.0dB(144MHz)5.5dB(430MHz) is an Rftech fiberglass antenna for Two-way Radio, Industrial IoT. It is selected for projects that need a defined RF band, practical mechanical integration, and a clear model reference for sampling, quotation, or customization work.

The GL-NL550 configuration lists 144/430 MHz operation with 3.0 dB(144MHz) 5.5 dB(430MHz) gain, UHF PL-259 connector support, Connector Mount installation, and 680*90*30mm dimensions where applicable. These values help engineers check electrical fit, enclosure space, cable routing, and mounting constraints before requesting samples.

Key Features

• 144/430 MHz operating coverage for vhf&uhf antenna applications.
• 3.0 dB(144MHz) 5.5 dB(430MHz) gain rating for model-level RF comparison.
• UHF PL-259 connector configuration for integration planning.
• Connector Mount installation style for device, enclosure, or site deployment.
• SKU GL-NL550 reference for sample requests, drawings, and quotation support.

Electrical Specifications

The table summarizes the published product parameters for selection review. Confirm final limits, tuning margin, and test conditions with Rftech when the antenna will be used in a new enclosure, vehicle, gateway, meter, or outdoor installation.

Mechanical and Installation Notes

GL-NL550 should be checked against the available mounting surface, cable route, connector orientation, nearby metal, ground plane size, and expected service environment. The listed Connector Mount format and 680*90*30mm mechanical reference help determine whether the antenna can be installed without stressing the cable, connector, radome, or PCB interface.

For compact antennas, small changes in housing material, adhesive position, cable bend radius, or metal clearance can shift VSWR, bandwidth, radiation efficiency, and measured gain. For fiberglass, magnetic, rubber, screw, Yagi, PCB, and panel formats, review the final installation position before production approval.

Typical Applications

GL-NL550 144/430MHz Fiberglass Antenna 3.0dB(144MHz)5.5dB(430MHz) can be used in Two-way Radio, Industrial IoT and related RF systems when the operating band and connector arrangement match the end device. Typical selection work includes LoRaWAN gateways, industrial IoT terminals, smart metering, remote monitoring, telemetry, broadband equipment, RF links, and wireless device integration.

Project teams should match the SKU to the target frequency plan, required coverage area, cable length, mounting surface, connector preference, environmental exposure, and expected order quantity. Rftech can support model selection, sample preparation, tuning review, and custom cable or connector requirements.

Compliance and Environment

Where ROHS, material, ingress protection, humidity, temperature, lightning protection, vibration, or radome information is listed, use those values as part of the product qualification checklist. Outdoor, high-humidity, high-vibration, and long-life programs should confirm sealing, mounting hardware, packaging, and inspection requirements before mass production.

Engineering Selection Notes

Before ordering GL-NL550, compare operating frequency, gain, VSWR, impedance, polarization, connector, cable, mounting method, and mechanical size against the real installation. Antenna performance should be reviewed in the final device or site position because nearby materials, cable routing, and installation height can affect tuning and coverage.

Sampling and Customization Support

Send Rftech the SKU GL-NL550, target frequency, mounting space, connector preference, cable length, expected quantity, and application environment when requesting samples or quotation support. The team can review custom cable, connector, bracket, label, packaging, tuning, and technical file requirements for the project.
