GatesAir Maxiva Multi Compact
Television has been around a long time, and while it’s still viewed on your television set using multiple distribution methods, it’s also available on other screens as well. No matter which screen it’s on, distribution is the key, and a lot of that still requires transmission. If you doubt that, just turn off your broadcast transmitter near the end of the Super Bowl.
