Probably been asked before but here goes. Moving into a new place that has a twin LNB already installed and looks like two cables going from the dish but in the lounge there's only one satellite jack from what I can see. Any ideas how that works?
 
You should have 2 lines coming into the lounge. Ignore multiswitch comment above, has nothing to do with anything
Maybe the 2nd cable goes to another room, but if you want a PVR you will need both cables going to the lounge
Previous owners perhaps had 2 single view decoders with a line going to each room
 
I have a dual decoder with dual lnb. When I only connect any one cable, I only Rx 1 TV, not 2.
 
Surely a "normal" dual LNB can't be split to two decoders without some kind of multiswitch. Anyone know if there was ever an LNB that was single but split to two cables at the LNB itself i.e. to providing a feed to two standard decoders?
 
Also, if the setup is not compatible with the PVR, what do you think would be the best way to sort it out? I was thinking of converting one cable to SatCR for the loung with a legacy output on the other cable, if it's going to another room. This is cost in hardware but no additional cabling (or labour) required to get the second feed to the lounge.
 
Maybe the previous owners had xtraview installed. When you have xtraview installed using the single decoder you only need one satellite feed per decoder so maybe the second satellite feed is in a bedroom/kitchen/office,etc. That would be the only viable reason so Smurfatefrog is 100% corect.

A normal dual LNB can be used to convey two different satellite. A normal single view decoder only requires one satellite feed, thus you can use two single view decoders with a dual LNB.

For A PVR you can only use the 2P PVR not the 4 Tuner version (The 4 tuner requires 4 satellite feeds where as the 2P Version uses two satellite feeds.)

It is not possible to split a single LNB to two different decoders as it locks onto one polarization either vertical/horizontal per channel thus two decoders cannot function correctly using a single LNB.
 
I've finally had another look at the installation and there are definitely two cables running from the LNB and the into the wall. Inside the lounge there's one one satellite jack in the wall plate. There is also an RF jack in the wall plate with an RF cable in the main bedroom. I guess this is the same RF cable. Apparently the dish serves more than one home, this is in a security complex. My understanding of a twin LNB is that you can't just "split" the signal (i.e. one cable to one house and the other to different house) so I don't see how a twin LNB signal can result in only one jack in the lounge. Unless this is one of those "fancy" installs where all the required signal information is carried over one cable. Any thoughts?
 
You should have mentioned that this is a complex. Changes things. I can't give you any advice, without knowing what equipment is being used to distribute the signal. Speak to body corp/managing agent to find out if the installation is HD and XtraView compatible. They will also have a preferred installer, should something need to be done to accommodate your needs.

Maybe you and your neighbour are sharing one dish, hence you have one cable and he has the other
