To make it really simple, hook up your antena directly to the coaxial outlet on back of t.v. Use the HDMI hook up for sattellite. When you want antena, simply use the remote that came with the t.v and click t.v. When you want sattellite click HDMI. Modern t.vs have multiple outlets, and you can hook a different source to each, such as one for CD players. Again using the remote, you can switch to the CD player.
