High Performance 5dBi 433MHz Whip Antenna with SMA Connector

Product introduction

1.Full Multiband Spectrum Coverage – Supports 433MHz (short-range control), 868MHz (EU SRD), 2.4GHz Wi-Fi/Bluetooth, and all major cellular bands (2G/3G/4G) from 890 to 2700MHz. This single antenna replaces multiple dedicated units, simplifying inventory and installation.

2.Stable 5dBi Omnidirectional Gain – Provides a uniform 360° radiation pattern, ensuring reliable signal transmission in all horizontal directions. The 5dBi gain strikes an optimal balance between coverage range and signal shape, perfect for both indoor and sheltered outdoor deployments.

3.Ultra-Low VSWR ≤ 1.5 – Guarantees exceptional impedance matching with minimal signal reflection. This not only maximizes radiated power but also protects your sensitive RF transmitters from back-reflected energy, extending the lifespan of your equipment.

4.Durable Whip Design (Φ18×220mm) – The elongated 220mm housing enhances vertical radiation efficiency and reduces detuning effects caused by nearby metal objects or mounting surfaces. Its rigid, lightweight construction resists bending while maintaining consistent electrical performance over time.

5.High Power Tolerance (50W) & SMA Connectivity – Handles up to 50W of input power, making it suitable for both low-power IoT modules and high-output professional radios. The industry-standard SMA male connector ensures instant, secure attachment to most commercial receivers and transmitters.

●Industrial wireless data terminals, SCADA remote units, and utility meter reading devices.

●Vehicle-mounted tracking systems and temporary emergency communication relay stations (with magnetic base adapter).

●Laboratory RF testing, signal monitoring equipment, and portable spectrum analyzers.

FAQ

Q: What frequency bands does the GL-D009 support?

A: It supports 433MHz, 868MHz, 2.4–2.5GHz, 890–960MHz, 1710–2170MHz, and 1710–2700MHz – covering sub-GHz SRD, Wi-Fi, and global cellular LTE frequencies.

Q: What connector is fitted on this antenna?

A: It comes with a standard SMA male (plug) connector. (Reverse-polarity or female versions are available upon request for custom orders.)

Q: What are the physical dimensions of this whip antenna?

A: It measures 220 mm in total length with a diameter of 18 mm (Φ18×220mm).

Q: Is this antenna better than a flat patch antenna for my system?

A: The whip design offers a true omnidirectional horizontal radiation pattern and performs more consistently on different mounting surfaces, whereas flat patches are more directional. For moving platforms or central hubs, the whip is usually preferred.

Q: Can I install this antenna outdoors?

A: It is designed for indoor or sheltered applications. For permanent outdoor use, please place it inside a waterproof radome or protective PVC housing to prevent weather damage.

Q: How does low VSWR (≤1.5) improve my system?

A: Low VSWR means less power is reflected back to the transmitter. This gives you stronger transmitted signals, longer communication range, and lower heat generation in your RF power amplifier.
