Difference between TV Splitter and a Tap

    I have NTL phone but want to split the NTL analogue signal in the most efficient way possible without degrading the signal quality on the line. The NTL technician gave me a splitter/tap as below:

    He told me to use the "in" for the main line in and the "out 2.2dB" to the modem and the out "Tap 6.5dB" to the TV. Does anybody know the significance of these different values?

    The problem is I need more than two outputs, so I was planning on using the 6-Way splitter as below to get more than two outs.

    Would I be best to use just the splitter or should I connect the Tap to the splitter so that the best signal goes to the modem/router?

    I think one is attenuated.
    The problem is if you split your signal 6 ways, it might make it too weak at each endpoint.
    You might need a booster, although I'm not sure how effective they are.

    Cheers. Looks like it - with the out 2.2 dB being the better signal? (better than the Tap 6.5dB?) Is the dB a measure of teh loss or the output?

    have tried a few over the years and never have much joy. Begeinning to think that you are better off making good connections that don't allow too much leakage.

    Yes, the 2.2bB is stronger signal..
    dB is a measure of the loss.. a 3dB attenuator means the signal strength is halved.
    The strongest signal would be the input to the splitter, so might be the best one to split.
    Generally I don't use splitters, I just strip & solder, because the more connectors/touch contacts in the system, the higher the losss.
    There's probably a side effect to my strip/solder method.. certainly splitting my current cable system 3 ways with this method. has lead to signal breakup on occasions..

    what i would do is leave the two way split one the modem the other tv.out of the back of the tv/digi box/video/(or whatever you have) then split the signal to the other points.
    As for bosters on cable they generally dont work.There is a certain amount of power coming down the cable so if you put a booster on it ,it interferes with the signal.I recomened to a customer throw away your booster get a standard 4 way co axial splitter!
    She got better pictures all round
