Satellite F-splitter or two cables..

    I didn't think it was possible and there seems to be be conflicting reviews on the Amazon website can using a satellite F-splitter behind the TV save having to run two coax cables to a twin LNB on the dish.

    Or is it better to just run two cables ....

    You can use a splitter to feed a twin-tuner receiver from a single LNB output, just use the right kind. (And hope your signal is good enough to survive splitting losses: a decent setup for the satellites at 28 degrees east should be well able.)

    Some receivers have an internal loopthrough & can feed both tuners from a single LNB feed, without a splitter e.g. Humax HDR. You won't get full watch/record flexibility but it will be a better choice of channels than if you are limited to using 1 tuner.

    What kind of receiver do you have?

    Ok don't have a receiver yet looking at the Humax HDR ones but ...there expensive and wonder if l really need or watch that much that a lower cost. ..might just go for it and move it from the nice to have to have .....treat myself 😊

    thurston can you explain in a bit more detail how you can split a satellite signal and name the make of splitter etc. Why do people use quad lnbs, twin lnbs, octo lnbs if one can split a sat signal!!

    My understanding is that a sat lnb gets 2 commands one of 13volts for a vertical channel and 18v for a horizontal. So if you split the signal how can the lnb cope with 2 lots of voltage??

    A foxsat will need too independent cables to work property a splitter will not suffice..

    If you cannot get a second cable to the room and the cable already in place is of RG6 or ct100 standard you can use a global stacker/destacker to allow 2 signals be sent down the one wire and split back out once it reaches the room required.

    Yes, independent feeds are the only way to get the full flexibility from the 2 tuners. The Foxsat or HDR don't need a splitter anyway, as they have loopthroughs: external on the Foxsat, internal on the HDR.

    Use a splitter that blocks the DC & 22 kHz control signals on 1 leg: something like this. The tuner connected to the power-passing leg will control the LNB, with the other being limited to transponders of the same band & polarity.

    If you didn't block the control signals from 1 of the tuners, the tuner sending 18 volts (h. pol.) &/or 22 kHz (high band) would always win any conflict.
