<br>
</div>Yes, and no. Depending on the amp (and the internal splitter),<br>
there may be large return losses that impact two-way services<br>
such as cable modems and cableco STBs due to the upstream<br>
signal being attenuated. As with all else, your signal will vary.<br>
If you are using a Cable Modem, and want an amp for a largish<br>
number of downstream devices, it is often suggested that you<br>
use a passive two-way splitter with one going to the CM and<br>
the other going to the amp. This is not needed if you use<br>
MATV/CATV quality amps with appropriate return path<br>
designs, but those amps are a lot more money than most<br>
want to invest (and are often hard to source). btw, also be<br>
careful about the supported frequencies. Some cablecos<br>
are starting to use frequencies towards 1Ghz (and some<br>
amps top out at the (older) 850Mhz levels).<br>

Typically amplifier circuitry is not designed to handle the return path. And your right about the frequencies, my cable company doesn't broadcast anything above 849Mhz currently, and I suspect that with Switched Digital Video they won't be, but the possibility is always there... so a GHz capable amplifier is recommended unless your sure you don't need it now and are willing to replace it if you need it in the future.</div>
