Hi guys. I have an older Samsung HD "ready" CRT tv set that doesn't have a built in ATSC tuner. I seems very hard these days to find hd set top boxes because most newer tv's have built in tuners. I just purchased an hd antenna and am trying to find an inexpensive way for me to be able to use it with my tv. I was looking on eBay and a guy is selling the Samsung SIR-TS360 Directtv receiver boxes for like $50. Would this work for me and allow me to receive over the air local HD channels without subscribing to directtv service? Thanks in advance for the help.
