2.4GHz External WiFi Antenna 2dBi SMA to IPEX Extension Cable

2.4GHz WiFi Antenna 2dBi – SMA Male + IPEX Cable for ESP32 / ESP8266

This 2.4GHz external WiFi antenna with 2dBi gain is designed to improve wireless signal performance for WiFi modules, IoT devices, and embedded communication systems. Combines a compact stick antenna with an SMA connector and an SMA-to-IPEX extension cable — flexible installation and stable RF performance.

Operates in the 2.4GHz ISM band — suitable for ESP8266, ESP32, and similar wireless modules that require an external antenna via IPEX interface. Widely used in smart home devices, industrial control systems, gateways, and custom IoT hardware. The IPEX-to-SMA cable lets you route the antenna away from the enclosure for improved signal vs PCB-trace antennas alone.

Key Features

• 2.4GHz WiFi frequency band support.
• 2 dBi gain for improved signal strength and coverage.
• SMA male antenna + SMA-to-IPEX extension cable.
• Compact stick antenna design for easy integration.
• Stable RF performance for embedded and IoT applications.

Typical Applications

• ESP32 / ESP8266 modules — upgrade WiFi range vs onboard PCB antenna.
• Smart home devices — door cameras, sensors, hubs.
• Industrial gateways — IoT data aggregators at the edge.
• Custom IoT hardware — production designs where external antenna mount needed.
• Bluetooth / Zigbee devices — 2.4GHz band compatible (verify chipset spec).

2.4GHz Antenna Specifications

FAQ — 2.4GHz WiFi Antenna

Q: Will it work with ESP32-CAM that has an IPEX socket?
A: Yes — most ESP32-CAM and ESP-WROOM-32 development boards have a U.FL / IPEX antenna socket alongside the onboard PCB trace antenna. Snap the cable's IPEX end onto the socket, screw the SMA antenna onto the cable's SMA end. Typically requires a 0Ω resistor swap on the dev board to route signal to U.FL instead of PCB antenna.

Q: 2dBi gain vs higher gain (5 / 9 dBi) — when to upgrade?
A: 2dBi is the standard compact stick antenna. 5+ dBi means a longer / directional antenna with reduced beam width — more range in one direction at the cost of less coverage in other directions. For most embedded WiFi designs, 2dBi omnidirectional is the right choice.

Q: Cable length included?
A: Standard SMA-to-IPEX extension cables are typically 10-15 cm. For longer runs (50cm+), use coax-quality cable to minimize signal loss at 2.4GHz.

Q: Bulk pricing for production runs?
A: Yes — email contact@lys-sz.com with your quantity for tier pricing.
