Passive TV Splitter issue

    I purchased a 4-way passive splitter to send saorview to different points in the house.


    At the moment, I have the cable from ariel to tv joined together with an F Connector coupler. Ariel is in the attic. Haven't had any signal problems in the 2 years i have it set up.

    This morning, I changed it over to use a passive splitter. No signal to tv unfortunately.

    A couple of questions. I only have the one cable out of the splitter...does that make a difference? I couldnt see why it would...but do I need more that one Out to "split" the signal.

    Would I be right in thinking that a powered distribution box is what im going to need if I cannot get a signal?

    Would there be any other reason that the signal not being strong enough to split why TV wouldnt be picking up anything?

    Your signal mustn't be strong enough for splitting 4 ways. You will need amplification of some kind: either the distribution amp. you already mentioned or, a low-noise 'masthead' amplifier, which would be better with a weak input signal.

    The masthead type can be powered remotely, so you don't need a power outlet in the attic & are available in multi-output or single: single could be used along with your splitter, provided the splitter passes DC power from at least 1 of the outputs to the input.

    A splitter will reduce the signal by about 7db to all points, it is possible your signal was just good enough to begin with for the one tv, so as already suggested by both yourself and Peter you will need a UHF distribution amplifier that you can plug in as close as possible to where all your tv connections are in the attic.

    So what is the difference between using a four-way splitter in this manner and using a two-way splitter which is working?

    It might be a faulty splitter?

    A 2 way splitter lose around 4 dB whereas a 4 way splitter loses around 8dB.
