DNC-2122 Waterproof Dual-Band RP-SMA Antenna 2.4GHz / 5GHz
Waterproof WiFi Antenna for Wet Conditions, Cameras, Drones, Security Systems, and Professional Video Equipment
The DNC-2122 Waterproof Dual-Band RP-SMA Antenna is a compact, durable antenna designed to maintain stable WiFi connectivity in wet environments. It supports 2.4GHz and 5GHz bands and is suitable for professional cameras, splash bags, outdoor security systems, FPV drones, wireless devices, and marine-related installations.
This antenna is especially useful when wireless communication is required in areas exposed to rain, moisture, splashing water, or harsh outdoor weather.

Key Features
- Dual-Band WiFi: Supports 2.4GHz and 5GHz frequencies.
- Waterproof Design: Built for wet, splash-prone, and rainy environments.
- Omni-Directional Coverage: 360-degree signal coverage for stable wireless communication.
- RP-SMA Female Connector: Compatible with many WiFi devices, cameras, routers, and WLAN systems.
- Built-In Water Block: Helps maintain housing vacuum integrity and adds protection against water ingress.
- Professional Applications: Designed for cameras, drones, security systems, and wet-environment wireless setups.
Important Note About Underwater Use
This antenna is waterproof and submersible, but WiFi signal transmission does not work effectively underwater. It is designed for wet environments, splash bags, rain exposure, and surface-mounted systems where the wireless signal path remains through air.
