2>"I need a reliable Wifi connection for my laptops. When the internal adapters weren't always good enough, I bought an external USB adapter/antenna. And for even more challenging environments the adapter/antenna can be extended with these cords. I don't believe the cord itself provides any antenna effect. However, being able to extend 6 feet closer (or just higher) to the signal can sometimes be a key upgrade. And if you ever need to use a laptop in your car, it makes a huge difference to be able to extend your antenna up and out the window and onto your roof.
