This mobile, fully automatic satellite system for RVs makes on-the-go satellite TV watching a breeze. When you reach your destination, press a button on the positioner, and the 18" antenna automatically rises. Enter the nearest city, your current elevation, or latitude and longitude and the antenna rotates until it finds a crystal-clear signal. When you're ready to travel, press another button and the antenna lowers to a compact 9" high. Easy to install. LNBF included. Works with DIRECTV® and DISH Network™ systems.
