I am currently living in the Philippines. I bought my Samsung Model UA40H5100 tv in the Philippines. My television does not have a RF coaxial input jack, it has what looks like a RCA input jack. I have tried to find out from SAMSUNG and have looked at their site with no result as they only show a coaxial RF input with threads which this does not have. I therefore can not plug in a antenna, or even use cable. I am using the two HDMI inputs one for my computer and one for my PS4. This antenna input jack states that it is indeed the antenna input jack, as it is written on it, but it is not a RF Coaxial tv antenna input jack. So your answer does not fit for me! I only contacted Samsung today so I have no answer from them directly. I did look at their How To guide which shows a RF coaxial antenna input jack...grrrrrrrrrrrrrrrrrrrrrrrrrrr~
