A:Answer My apologies for the late response. The 4MAX is a longer range antenna. Purchasing the 2MAX over the 4MAX is greatly determined by where you live and where the towers are located. If you have stations that are within 70 miles of your location, I would recommend the 4MAX, if you have stations within 60 miles, I would recommend the 2MAX. You can see the number of stations and where the towers are located by clicking on this link and entering your zip code. https://www.antennasdirect.com/transmitter-locator.html.
