Lisa, just to echo TowerGuy's recommendations, installing a Winegard 7698P antenna at a height above ground level of at least 30 feet is the way to go. Install his recommended preamplifier as close to the antenna as possible (right on the mast, if possible.) The preamp's power supply can be installed between a TV and the splitter or between the splitter and the antenna (recommended.) The power supply injects DC onto the coax that drives the preamp.

Each TV can tune to whatever channel they want - you are feeding the same mass of RF signals to all of them. Having multiple TVs is the key reason to avoid using a rotator - each TV would be limited to the signals in the direction the antenna is pointing.

One quality control matter: I recommend you use the "start MAPS" option to verify that the analysis tool is placing your location at the right spot on your street. You'll get a Google map with a red icon that points to where it thinks your location is. Hopefully it is right, but if it isn't, drag the pointer to the right place. Switch to satellite view and zoom in. Based on some signal plots, if you have to move the pointer east, then predictions will be worse.

Once you get set to the right point, try different antenna heights until the NMs for the signals from each of the networks pops up to over 10. Click the radar plot button and share that report with us (if it's different than what we've seen already.)

Good luck!

PS, if the pointer is in the right spot given your address, then be sure to mount as far south and west as you can. Going in those directions will improve the signal strenghts available from the stations to the north of you.
