NO, your analog TVs will not use the signal from your antenna, because they will not recognize the digital signal being broadcast by nearly all OTA stations. The antenna, unless there is something wrong with it, will work with a digital signals just as well as it will work with analog. All you really need is a small digital converter box from Walmart or BestBuy for each TV. The box will take the digital signal from your antenna and convert it into an analog signl for your TV. Works great. However, do consider changing out the TV whenever possible, because the new one are much lighter, have a lot better picture, are fairly cheap, use a lot less power, and will give you a high definition picture if the station is broadcasting in HD, which most do by now. The new TVs will not require the converter box, and will work with both antenna and park cable if available. In my case, I had the choice between a converter box for about $50, or a new TV for about $150. the picture on the old analog was low def and fuzzy, Now the new TV is bright and sharp, and picks up a lot more channels than the old one would. A new TV will typically pick up more and weaker channels that the converter box will.
