Question on cable signal loss vs splits

207.178.211.68

DWPC

I have to relocate the cable outlet for our primary TV. I'm trying to avoid a major cable pulling job. Does it matter whether I tediously re-route the existing leg from the 4-way splitter in the attic to the new location (25 ft), or just split the cable (to a PC) in the room on opposite side of the adjacent wall.

The cable service simply splits the main signal to provide the no. of outlets needed, so why not just add a splitter where its most convenient? Does one 1x4 splitter provide superior signal to two 1x2 tee splitters in parallel?

As the guy who jumped off the 20-story building shouted as he passed the 10th Floor "So far..so good!"

They also sell 4 way powered splitters.
This unit out performers the powered amplifier from the cable company.
Cablevision or Brighthouse.

How many cable outlets total do you have in the house? 1 four way splitter is better than 2 two ways in series. If you have more than four outlets already. The best bet is to add a splitter that is amplified.
Depending on the cable signal strength, you could split off from your existing splitter without issue. The golden rule in cable is no more than 4 outlets to a single drop from the tap. Try it..if your picture shows any degradation..buy an amplifier. I would'nt split of the line feeding your modem. The internet connections can be a little sensitive in some cases.

  We have a total of 5 outlets. Four from a 1x4 splitter (for 4 TVs) plus one for the computer, which originates from a 1x2 splitter outside before the 1x4 splitter in the attic for the TVs. I'm disconnecting one and adding a new one, i.e., the net no. of outlets will remain the same.
  
  Signal strength doesn't seem to be an issue now as I have no problems with analogue or digital TV or cable internet. Would it help to short the coax connectors on unused outlets?

    No not really..no need to bother with shorting the unused connections. If you've got good reception now..you should be fine. I would leave the other line and just unplug it , drop a new one where you wanted it. That way in the future,if you decide to move to another home. The original outlet can be reactivated for the new owner.
    If this seems too much of a run, splice into the old outlet and use it.
    Yeah you shouldn't have any problems with the internet as they split the signal before the main splitter. This is common, it helps insure your modem will get the best signal. So even if your picture quality doesn't look great..you'll still have great internet service. ;-)
    Too bad you're not closer, I would just give you one of my unused 8 port powered amplifiers.
