A:
All over the air broadcasts are now via a digital signal. If your older TV (say around 2005 or earlier) only has a NTSC tuner (check the TV manual) then you will need a digital to analog converter in addition to the antenna. I haven't seen an analog antenna sold new for years but if you find one and have an analog only TV then it should work. If your TV has a digital tuner (QAM) then you need a digital antenna and the RCA will work fine.
