Comes with a dual USB cable which provides extra power to the antenna. I installed as directed and connected both cables to my laptop, after which the laptop failed to see the antenna. I tried to connect using the data cable but to no avail. I also tried connecting to the USB 3.0 port with the same negative results. Subsequent communication with K. Crane revealed that the cable itself was defective and I replaced it with another cable. The antenna then worked as advertised until last week when it began to disconnect intermittently from the computer. What I mean by this is that the cable stayed connected, but the computer "forgot" that the antenna was connected. Now when I plug the antenna into a power outlet, I get the error message "USB Device Faulty". I see the antenna connect for a split second and then it fails. I've verified the integrity of the cable (no cat tooth marks) by plugging it into my DSLR and leaving it plugged in for hours and I've experienced no data loss or disconnection. So if it's not the cable, the USB ports or the laptop, the source of the problem must be the antenna. Look, it works great for two months, but it burns down and you're left with a really bad paperweight.
