What Qualifies as a SWM System?
A SWM (Single Wire Multiswitch) System consists of either a satellite dish with SWM Technology built in, or a multiswitch with SWM Technology.
SWM Dishes are identified by having a single output, and are the only dish to require a power supply. Examples of SWM Dish are the SL3-SWM and SL5-SWM
A SWM Switch takes all four outputs from a satellite dish, and produces a single output, which can be divided up with splitters. The benefit of this system is only having to run one line to a DVR, which normally requires two lines. It also allows for a distribution with splitters, similar to how cable TV is setup.
Another benefit of SWM comes with the addition of a DECA Adapter, that feeds internet into one of the outputs from a SWM Systems. This enables every receiver to have a network connection through a single coax.
With the combination of a SWM technology and DECA, you get a DIRECTV Connected Home which features MRV or Multi-Room Viewing.
This enables a house with a HD-DVR to be controlled by other HD Receivers in the building.
