Product Introduction

1. Complete Multi-Frequency Band Compatibility

Covers a full range of radio spectrums: 433MHz for short-distance remote control, 868MHz European SRD band, 2.4GHz Wi-Fi & Bluetooth, plus full-spectrum 2G/3G/4G cellular frequencies spanning 890MHz to 2700MHz. This all-in-one aerial eliminates the need for multiple single-purpose antennas, cutting inventory costs and streamlining installation workflows.

2. Consistent 5dBi Omni-Directional Signal Gain

Delivers a uniform 360-degree signal radiation layout, delivering dependable wireless signal transfer across every horizontal angle. Its fixed 5dBi amplification strikes an ideal equilibrium between signal broadcast distance and radiation coverage shape, fitting indoor setups as well as covered external deployment scenarios.

3. Ultra-Low Standing Wave Ratio VSWR ≤ 1.5

Achieves outstanding impedance matching with negligible signal bounce-back. This feature not only maximizes output RF power but also shields delicate radio frequency transmitters from reflected signal energy, lengthening the service life of your communication hardware.

4. Sturdy Rod-Style Construction (Φ18×220mm)

The extended 220mm outer casing boosts vertical radiation efficiency and mitigates frequency detuning triggered by adjacent metallic components or mounting substrates. Its stiff, lightweight build resists bending deformation and retains stable electrical specifications throughout long-term operation.

5. 50W Maximum Power Load & Standard SMA Terminals

Capable of sustaining up to 50W input power, compatible with both low-energy IoT circuit modules and high-power professional radio transceivers. The widely adopted SMA male plug enables quick, stable pairing with most mainstream commercial receiving and transmitting devices.

Application Scenarios

●Wireless anti-theft alarm main control panels and boundary trespass alert monitoring equipment

●Smart household automation gateways and Zigbee/Thread edge routers requiring combined sub-GHz and 2.4GHz dual-frequency operation

●Factory wireless data terminals, SCADA remote monitoring units, and public utility meter data collection hardware

●Vehicle location tracking devices and temporary emergency signal relay stations (magnetic base adapter sold separately)

●Lab radio frequency testing instruments, signal monitoring gear, and portable frequency spectrum analyzers

FAQ

Q: What radio frequency spectrums can the GL-D009 aerial operate on?

A: This antenna supports 433MHz, 868MHz, 2.4–2.5GHz, 890–960MHz, 1710–2170MHz and 1710–2700MHz, covering sub-GHz SRD bands, Wi-Fi signals and global 4G LTE cellular frequencies.

Q: What type of terminal port is pre-installed on this antenna?

A: It is customized with a standard SMA male plug. Reverse-polarity SMA or female SMA terminals can be for bulk orders on demand.

Q: What are the exact physical measurements of this rod antenna?

A: Its overall length reaches 220mm with an outer diameter of 18mm (Φ18×220mm).

Q: Does this rod antenna outperform flat patch aerials for my communication setup?

A: The whip-style structure provides full horizontal omni-directional signal radiation and maintains steady performance on various mounting bases, while flat patch antennas feature directional signal output. This rod antenna is the top pick for mobile equipment or central signal hubs.

Q: Is this antenna suitable for open-air exterior mounting?

A: It is engineered for indoor or sheltered external deployment. If you plan permanent uncovered outdoor installation, house the antenna inside a weatherproof radome or protective PVC shell to avoid corrosion and environmental damage.

Q: What performance benefits does a low VSWR rating (≤1.5) bring to my wireless system?

A: A low standing wave ratio reduces signal power reflected back to the transmitter unit. This results in stronger broadcast signals, extended communication coverage distance, and less heat buildup inside your RF power amplifier module.
