CANTenna (Standard / Soup Can)
$50
Product Description
This is a 2.4 GHz cantenna designed for Wi-Fi range extension. It's especially useful for those seeking much-needed longer range, and it's ideal for pentesters (penetration testing, ethical hackers, white hat hackers). Or anyone else looking for range out of their Wi-Fi adapter.
It works very well, providing great range and excellent penetration through walls for a reliable connection. I build these myself and ensure a professional finish.
Technical Specifications
- Connection Type: Female N-type connector. You will need a Male N-type to SMA connector for your Wi-Fi card.
- Build Quality: Accurately built, adhering to the 1/4 wavelength guide for the can's diameter. This ensures precise functionality (it's not just a can with a random metal pole placed inside).
- Gain: 14dBi gain
- Beam Width: 22-degree beam
- Range: Up to 300 meters
- Performance: Performs well through obstacles like trees, effective without direct line of sight
- Mount: 1/4" thread mount (NOT 3/8")
Package Includes
- Custom-built 2.4GHz cantenna (BLACK finish)
- Tripod included
- N-to-SMA wire included
