The
> upstream connection I mean.
There are better splitters and worse splitters. The typical splitter that
most people buy is just that, simple. And as Jim said, each split adds
resistance and reduces the signal. If you have a 2-way splitter you get 1/2
the original signal. If you have a 3-way, each gets 1/3. Most cable
companies have policies on how many "TVs" they allow (usually 3), but a
split for the cable modem counts toward that amount.
There are amplifiers that will enhance the gain on the signal. You can buy
one of these at Radio-Shack, BestBuy, HomeDepot, etc or online. They range
in price from about $30 to $120 and from what I've read and the cable techs
I've talked with, they don't differ in quality just price. There are some
though that offer a gain adjustment knob to control the amount of
amplification. One thing to keep in mind about amplifiers though is that
they amplify noise as well as signal. So if you have a problem signal
amplifying it may only amplify the problem. But they work well enough for a
clean signal. Also, these can potentially interfere with cable modem
upstream signals, so you want to make sure to look for a bi-directional
amplifier. I have one and it works fine when I use it.
There are also amplified splitters/distributors. They build the amp inline
with the splitter. For instance, I have an 8-way split in my house. I don't
have 8 TVs, but I have jacks everywhere.
And since you asked about sending a signal from your TiVo to other TVs, some
distributors have multiple inputs too. So you can get a 3-way in/8-way out
for instance.
