Product introduction

1.Ultra-High Gain 28-30dBi

Delivers exceptional signal amplification, far exceeding standard antennas. Perfect for long-distance or weak-signal environments, significantly improving reception and transmission range.

2.Wide Multi-Band Coverage

Supports 890-960MHz, 1710-2170MHz, 1710-2700MHz, and 2400-2500MHz, covering GSM, CDMA, 3G, 4G LTE, and 2.4GHz WiFi – one antenna for multiple network types.

3.Extremely Low VSWR ≤1.5

Minimizes signal reflection and power loss, ensuring nearly perfect impedance matching. Improves RF efficiency and protects your transmitter from reflected power.

3.High Power Handling up to 100W

Robust design withstands 100W maximum input power, suitable for repeaters, boosters, and base station applications where high transmit power is required.

4.Compact Size with Flexible Connectors

Small footprint (29×74mm) allows easy integration into enclosures or portable devices. Comes with SMA or FAKRA connector options – compatible with common RF modules and vehicle-grade systems.

Application Scenarios

●Cellular Signal Booster Systems – Installed indoors or outdoors with a repeater to amplify weak 2G/3G/4G signals in rural areas, basements, or remote buildings.

●Long-Range WiFi Bridge – Paired with 2.4GHz access points to extend wireless coverage between buildings or across campuses.

●IoT & Telemetry Devices – Embedded into industrial modems or data loggers that require high-gain multi-band reception in harsh RF environments.

●Vehicle-Mounted Communication – With FAKRA connector, ideal for in-vehicle cellular amplifiers, fleet tracking, or emergency response systems.

●Test & Measurement Equipment – Used in RF labs as a reference high-gain antenna for sensitivity tests or interference hunting.

FAQ

Q:What frequency bands does GL-E003 cover exactly?

A:It covers four bands: 890-960MHz (GSM/CDMA), 1710-2170MHz (3G/4G low band), 1710-2700MHz (4G high band), and 2400-2500MHz (2.4GHz WiFi).

Q:Is the gain really 28-30dBi? The size is very small.

A:Yes, the datasheet specifies 28-30dBi. This is achieved through helical (screw) design principles. However, please confirm with actual test reports for your specific deployment.

Q: Which connector type comes standard?

A:We offer both SMA and FAKRA options. Please specify your requirement when ordering.

Q: What is the maximum input power?

A:The antenna can handle up to 100 Watts continuous power.

Q: Is VSWR ≤1.5 across all bands?

A:Yes, the VSWR is ≤1.5 over the entire frequency range, ensuring excellent impedance matching.

Q:Is this antenna omnidirectional or directional?

A:Based on the ultra-high gain (28-30dBi) and screw/helical form factor, it is typically directional (helical beam). For precise radiation pattern, refer to the product pattern sheet.
