The antenna cable is not great if you want to significantly improve reception, I advise you to connect another cable to connect device (TV or other) is very important. I picked up a lot more channels with this technique, 34 channels on Freebox Revolution against 17 before with the original cable (he missed a lot, like Direct 8 and D17 for example). The cable I connected is however very long but it improves reception.
Why I bought this antenna? I could connect my TV to my rooftop antenna because too far in the house.
No problems at all, I recommend.
