Splitter with Cable modem

I will be helping a friend install a cable modem and setup cable Internet
service. He has the home install kit (Comcast). The kit shows the ins and
outs for the modem connections on the back panel.

My question is, can I use a standard cable splitter to split off the cable
from the TV to the modem? Or do I need some kind of special splitter since
the device is a cable modem?

Thanks,

-Frank

You can use any quality splitter rated at 900MHz or above.  The splitter
must pass signals in both directions but other than that, there are no
special requirements imposed by the cable modem.

However, avoid the ones labled GC or anything from your local Walmart.
Use the 2 way splitter provided in the installation kit. They are good
quality, and rated at 1GHz.

One problem with most retail splitters is that while they may be rated
5-900MHz, they usually start to roll off about 600MHz, right at the
cable modem downstream frequency. Truth in advertising should make them
read 5-900MHz, +-10dB. The one in the installation kit is flat from
5-1GHz, and has far better shielding. Besides, it is included in the
$1.00 charge for the kit.

  What is important for ANY digital service, TV or modem, is that it is
rated at least 5MHz-900MHz. Do not use an unrated splitter, or one rated
only down to 40MHz or so. Digital cable boxes and modems use the lower
frequencies for the upstream signal.

I connected my splitter on the cable from the pole/ then ran a separate line
to the cable modem.
