Payment: TT,Paypal,Westen Union before shipment

Product Introduction

1. Wide Frequency Range：The GLZ03 - 100 3G/4G antenna covers a broad frequency range from 698 - 960MHz and 1710 - 2700MHz. This wide - band coverage makes it suitable for various 3G and 4G networks, ensuring compatibility with different carriers and regions.

2. Decent Gain：With a gain of 3dBi, the antenna can effectively strengthen weak signals. This helps in improving the signal reception and transmission quality, enabling a more stable and reliable connection for 3G/4G - enabled devices.

3. Low VSWR：The voltage standing wave ratio (VSWR) of ≤2.0 indicates efficient power transfer. Low VSWR reduces signal reflection, which is crucial for maximizing the power delivered to the antenna and enhancing the overall performance of the communication system.

4. Versatile Mounting Options：Featuring screw mounting and L - type mounting, the GLZ03 - 100 offers flexibility in installation. It can be easily attached to different surfaces, such as walls, poles, or equipment, making it convenient for various applications.

5. Wide Operating Environment：Operating within a temperature range of - 40℃ to 60℃ and a humidity range of 5 - 95%, the GLZ03 - 100 can function in diverse environmental conditions. This wide - range tolerance makes it suitable for use in different climates and locations.

Application scenarios

• Strengthen cellular signals in remote farms, construction sites, or IoT sensor networks.

• Enhance mobile connectivity for RVs, boats, or fleet vehicles.

• Support industrial equipment requiring stable 3G/4G data transmission.

• Improve signal reception for off-grid security cameras or monitoring systems.

FAQ

Q: Is this antenna compatible with 5G networks?
A: No, it is optimized for 3G/4G/LTE bands (698-2700MHz).

Q: Can it be used indoors?
A: Yes, but it’s designed for outdoor/industrial environments due to its weatherproof build.

Q: Does the SMA connector fit standard routers/modems?
A: Yes, the SMA male connector is widely compatible with cellular devices.

Q: How far can it extend signal coverage?
A: Range depends on network strength and obstacles, but the 3dBi gain improves existing signals significantly.

Q: Is the cable length customizable?
A: The default is 3m RG58. Contact us for custom lengths.

Q: Can it handle lightning strikes?
A: While durable, we recommend using a surge protector for added safety in storm-prone areas.

Q: What tools are needed for installation?
A: Basic tools for screw/L-type mounting (e.g., wrench). No specialized equipment required.

Q: Does it work with MIMO systems?
A: No, this single-antenna model uses vertical polarization only. For MIMO, consider dual-antenna setups.
