Although described as a 2.4Ghz aerial, I found it works on both 2.4Ghz and 5Ghz with my TP-Link dual band wireless network card.
The only minor drawback is that the cable is only 1 metre long which means you don't have much choice as to where you place the aerial. My computer sits on the floor, which means my aerial only just reaches to my desk and has to sit behind my monitor. It would have been great if the cable was 2m as it would offer better choice for placement and maximise signal.
All in all though a good product that works much better than having three aerials sticking out the back of the computer.
