This "rubber duck" style antenna is a high-performance multiband terminal antenna specifically designed to support the latest generations of wireless technology: 5G cellular and Wi-Fi 6E. The combination of 4 dBi gain and the SMA Male connector makes it an ideal upgrade for devices requiring enhanced signal strength and coverage across multiple key frequency bands.
The term "rubber antenna" refers to the durable, flexible housing (often made of rubber or ABS plastic) that protects the radiating element, while "terminal antenna" means it connects directly to a device without an external cable.
Key Features & Supported Frequency Bands
A defining feature of this antenna is its ability to operate across a very wide range of frequencies to support all three major connectivity standards.
| Technology | Frequency Bands Covered | Purpose/Benefit |
| Wi-Fi 6E (Extended) | 5.925 - 7.125 GHz (The new 6 GHz band) | Provides access to clean, uncongested channels for ultra-low latency and multi-gigabit speeds. |
| Wi-Fi (Legacy) | 2.4 GHz (2.4 - 2.5 GHz) and 5 GHz (5.15 - 5.85 GHz) | Ensures backward compatibility with older devices and provides extended range (2.4 GHz) and higher speeds (5 GHz). |
| 5G / 4G LTE | Sub-6 GHz Mid/High-Bands (e.g., 600 MHz up to 6000 MHz, depending on exact model) | Supports the most common 5G New Radio (NR) and 4G LTE bands, crucial for cellular modem connectivity. |
High-Gain (4 dBi) and Form Factor
Gain (4 dBi): The 4 dBi gain is considered moderate to high for a compact rubber antenna. This gain helps boost the signal strength compared to the small, often low-performing stock antennas (which might be 0-2 dBi), leading to better reception, faster speeds, and improved connection stability without making the antenna overly bulky.
Rubber Duck Form Factor: This design provides a low-profile and durable solution, perfect for indoor routers or outdoor equipment where space is limited and protection against minor impacts is necessary.
Connector and Compatibility
SMA Male Connector
The antenna uses a standard SMA Male connector, which features a center pin and internal threads.
Function: It is designed to thread directly onto an SMA Female jack (which has a center sleeve/hole and external threads) found on the device.
Vibration Resistance: The threaded coupling ensures a secure, vibration-resistant connection, which is important for mobile or industrial equipment.
Device Compatibility
This antenna is a plug-and-play upgrade for various devices, provided they meet the following criteria:
Frequency Support: The host device (e.g., router, gateway, modem) must be designed to operate on the same multiple frequency bands (2.4 GHz, 5 GHz, 6 GHz, and required 5G/LTE bands) as the antenna.
SMA Female Port: The device must have an external SMA Female connector port to accept the antenna.
Polarization: It is typically an Omnidirectional antenna with Vertical Polarization, suitable for most access points and terminals.
Typical Usage Scenarios
This tri-band antenna is primarily used to enhance wireless performance in modern networking and M2M (Machine-to-Machine) communication.
Wi-Fi 6E Routers/Access Points:
Application: Replacing the stock antennas on a Wi-Fi 6E compatible router or wireless access point.
Benefit: Improves signal coverage, especially for the new, high-speed 6 GHz band, allowing Wi-Fi 6E clients to connect at maximum possible throughput and range.
5G/LTE Industrial Gateways and Modems:
Benefit: The broad frequency coverage ensures connectivity across different carrier bands, while the 4 dBi gain improves signal reliability in challenging signal environments (e.g., basement wiring closets, remote sites).
IoT and Embedded Devices:
Application: Used with devices like desktop PC Wi-Fi cards (with external antenna ports), development kits, or specialized IoT hubs that operate across multiple bands.
Benefit: Provides a compact, high-performance external antenna solution superior to tiny, built-in internal antennas, maximizing the device's wireless range and speed.
