Winegard SWM-840 (SWM-8) DIRECTV Multi-Switch Kit

The Winegard SWM-840 (SWM-8) Multi-Switch Kit enables DIRECTV receivers that require SWM-only technology to work with Winegard mobile satellite TV antennas that are not SWM-equipped. It provides compatibility between DIRECTV's SWM-only equipment and non-SWM Winegard mobile satellite antennas.
