Yes unless you get Cable Amplifiers with ACTIVE RETURN like a PDI 1100AR-6KV or 211AR-6KV or 407AR-6KV, Motorola BDA-K1-RA, Viewsonics VSMA608C-10R or Electroline EDA-FT08100
Yes that the rigth way to setup Cable Amplifiers and besure add Coaxial Lightning Surge Protector before going to the Amplifier, the reason why the Amplifier need be frist rigth off the main line that way all the Splitters will have more forward dB gain with out the loss.
just to clarify, you agree that the amplifier should be put after the cable modem split? It sounds like you are saying it should be at the closest part of the coax to the entry to your house, if possible (to reduce the amplification of noise). also, use a coax surge protector :)
OK, I think I understand. Unless I have an amplifier with active return, I should put the amp at the beginning of the cable.
Sounds like a cable amplifier might be just what I need, at least pending jph's tests.
OK, I think I had this mixed up. Active Return amps allow the cable modem's signal to be sent back out (instead of blocking or hampering the cable modem's frequency range). So, if I were having trouble with my cable modem, I might want to try an amp with active return, placed between the modem and the source.
My current situation is such that I don't think I have any speed or connectivity or synch problems with the modem (though I think the modem might be flaking out, it has over the last week spent on 2 occasions a few hours unable to synch with the cable provider). Other than this issue, I get about 8Mbps down and adequate up, I suppose.
SOURCE ---> 2way split (1000MHz) ---> 2 way split (1000MHz) ---> 3 way split to TV and the two inputs on my Hauppauge 1600
bedroom TV Cable Modem
I originally bought a cheapo 900MHz 3-way splitter, but that noticeably lower the already mediocre quality of a couple channels we care about, but even without the splitter I have choppy performance with QAM on my Hauppauge 1600.
I suppose I should get a 3-way amp to place after the 2nd 2-way split (after the cable modem)? Without running a bunch of more cable along the walls and ceiling, there's no way to move the TVs or Cable Modem around unfortunately. I realize this long line isn't ideal...
My only question is whether it would be worth getting an active return-enabled amp to place at the beginning of the run, as, intuitively to this non-electrical engineer, an amplifier will amplify everything including noise, and further down the line, past 2 splitters, there's going to be more noise to amplify. any thoughts?
