They should have specifications on older models letting you know if the TV is analog or digital. In that case grab the model number off the back of the TV and check the manufactures website. However, if you are anything like me, you have no idea where that owner’s manual is.

The specifications should let you know whether your TV is analog or digital. The easiest method to figure out what type of tuner your TV has is to look in the owner’s manual. Otherwise, the TV tuner is analog and you either need to buy a digital TV or a DTV converter box to get free TV with an antenna. To answer this you need to know if the TV has a digital tuner (also called a digital receiver.) If it does, then you do not need a converter box for your TV. Prices range from $30 – $80 for a DTV converter box based on the quality of the brand. It translates the digital signals being picked up by the antenna into an analog signal that can be received by your TV tuner. A digital converter box is a device that connects to your existing analog TV and your antenna.
