Rubber Duck Antenna

This Omni-directional All-network Compatible Rubber Duck Antenna features a standard SMA connector with 180° vertical bending and 360° horizontal rotation for flexible installation. It provides stable omnidirectional signal coverage across multiple frequency bands. Manufactured by Shenzhen Qianmu Communication Technology Co., Ltd., the antenna is built with a new environmentally friendly rubber housing and high-purity copper radiating elements, helping improve signal stability, connector durability, and compatibility with a wide range of wireless devices.

Working Principle and Measured Data

1.Operating Principle

This model supports all network bands.Rubber Duck Antenna Enables bidirectional conversion between full-band electrical signals and RF electromagnetic waves: High-frequency electrical signals from the device are transmitted via an SMA interface to a pure copper oscillator, which radiates 2G/3G/4G/5G cellular signals as well as 2.4G/5.8G WiFi signals outward. At the same time, the device can receive all types of wireless signals from the surrounding environment in any direction and relay them back to the device, enabling stable, bidirectional, and nationwide communication. The product features a standard 50-ohm impedance design.,Significantly reduces signal transmission loss across multiple frequency bands, effectively enhancing connection stability in complex environments.

Technical Specification Parameters

Real-world implementation cases

1. Overseas Security Brand Collaboration

A European surveillance brand purchased this 2G/3G/4G/5G all-network compatible Rubber Duck Antenna in bulk. After replacing the standard WiFi antenna, the offline rate of outdoor 4G surveillance devices was reduced from 18% to 2.3%, significantly improving network stability in remote areas with weak signal conditions.

2. Domestic Industrial IoT Projects

An industrial DTU manufacturer purchased 50,000 units of this all-network compatible Antenna in bulk. The antenna supports multi-band industrial terminals, effectively solving disconnection issues during 2G/4G band switching and reducing device communication failures by 76%.

3. Australian Agricultural Monitoring Project

A farm’s long-range 4G monitoring equipment equipped with this antenna achieved full signal strength within an 80-meter range in open environments. The system maintained stable multi-band communication under both high and low temperature conditions, eliminating nighttime disconnections and signal attenuation issues.

Comparative advantages over peers

Most Rubber Duck Antennas available on the market support only a single WiFi band and are not suitable for 2G/3G/4G/5G cellular applications. Many are produced by small contract manufacturers using lower-grade materials and lack full-band performance verification. As a professional China manufacturer and factory, Shenzhen Qianmu Communication Technology Co., Ltd. offers all-network compatible solutions with the following advantages:

Standardized Installation Guide

Step 1: Interface Verification

The standard SMA female connector is compatible with the male-pin interface of 2G/3G/4G/5G all-network devices. If you require an RP-SMA reverse connector, please contact the supplier for custom adaptation.

Step 2: Tighten the connector.

Tighten the hand-tightened nut gently clockwise; do not use forceful tools to tighten it. This will prevent the threads from stripping and the internal pin from breaking, ensuring smooth signal transmission across all frequency bands.

Step 3: Angle Adjustment

Bend at a 30° angle according to the device’s position – 180°; When installing outdoors or in areas with weak network signals, aim the device upward as much as possible to expand the coverage of the full-frequency band.
