DirecTV Multiswitch
" Looking for Easy Solution for your DirecTV Multiswitch? " What is a Direct TV Multiswitch used for? It is required whenever you connect more than two DSS receivers to a single Dual-LNB dish, or you connect multiple receivers to a multiple satellite dish or multiple dishes. This section is going to share with you how to connect a DSS antenna to multiple DSS receivers by using Direct TV multiswitch. Besides, it describes how to run both DSS signals and antenna or cable signals down a single coax! If you have been researching DSS, you've probably run into terms such as Dual LNB, Direct TV Multiswitch and Diplexer in reference to connecting DSS to multiple satellite receivers. There are several ways that you can view DSS programs on multiple TVs. We start out describing the minimum wiring you'll need in your walls, and then we go through some sample distribution systems, by increasing levels of cost and features :) The most important thing to understand about DSS systems is that the receiver box actually tells the antenna (dish) which channels it wants. The active part of a satellite antenna is called the LNB. In high-power DBS (Direct Broadcast Satellite) systems such as Direct TV and Dish Network, each channel is broadcast from the satellite with either a "left hand" or "right hand" circular polarization. An LNB can only receive one type of polarization at a time. Half of the channels are one polarization and half are on the other. The satellite receiver has a table (downloaded from the satellite) of which channels are on which polarization, so it "tells" the dish which polarization to select and deliver down the coax. It does this by placing a variable voltage on the cable. The figure below shows how you can break the "two receiver" barrier using a DirecTV multiswitch. The DirecTV multiswitch takes both cables from the dish and "shares" them with multiple receivers. It also takes in an antenna or CATV signal and, using built-in diplexers, combines it onto each of the outputs. Each output must run directly to one, and only one satellite receiver. (But it's ok if there isn't a receiver installed on every cable :P) At the other end, if you do have a DSS receiver, you split the DSS and VHF/UHF signals with a diplexer.
The multiswitch we carry amplify the satellite signal, but not the VHF/UHF/CATV signal. In order to support more DSS receivers, you can use more than one multiswitch. Each multiswitch will have to get feeds from both LMBs so each coax from the dish will have to have a DSS Signal Amplifier and KU band splitter. Be sure and connect each feed from the dish to the same port on each multiswitch or else they won't work right :P
Keep in mind that everything you know about VHF/UHF/CATV video distribution just doesn't apply to DSS configurations. I believe that our Verizon Direct TV Tips will be useful to you as well :) You are welcome to try our

When using a DirecTV multiswitch, you can count on needing a regular VHF/UHF/CATV amplifier between the combiner and the DirecTV multiswitch.
These drawings and explanations should give you enough to go on to configure your system. The VHF/UHF/CATV side of things can be as simple or elaborate as you want, but the DSS side must follow one of the layouts described here.
