Rookie question ,I have a duel output lnd ,3tvs ,can i tee into 1 cable to run 3 receivers which would allow 3rd TV,?

not really. Not without major limitations and risking frying the receivers.

but you can add a multiswitch, that would typicaly allow up to 4 receivers, with full functionality

What about a splitter ,is a multi switch simulator ?

What about a splitter ,is a multi switch simulator ?

a splitter is just that, it splits the signal. But with satellite, you have 2 polarities (Horizontal and Vertical) that are controled by the voltage on the coax. The LNBF transmits whatever polarity the receiver is asking for. So if you put a splitter , there are 2 cases:
- the splitter conducts that voltage on both branches, one receiver sends 18V, the other sends 13V. You could end up destroying one or both receivers
- the splitter passes only the voltage from one receiver, and blocks voltage from/to the other receiver. This is much safer and will half work. What I mean by that is that the receiver on the port which blocks the voltage, will work only if what you want to watch is on the same polarity and what the first receiver is tuned to. This would be very inconvenient in most cases

A multiswitch will instead always get horizontal on one LNBF port and Vertical on the other. and when a receiver connected to that multiswitch requests a polarity, the switch will connect it to the appropriate LNBF port automaticaly. It's like having a Quad-port LNBF

will that geosat 2x4 switch work with a titanium c138 lnb ?

will that geosat 2x4 switch work with a titanium c138 lnb ?

Generally speaking, no. The C138 is single output. You need a dual output lnb or lnbf with a multi-switch. The Titanium Satellite C238 would work.
