Re: transmit power for modems

It's the signal level put out by the modems. If you look at a spec sheet from a manufacturer they give you the return loss at frequency of a particular cable or equipment. It is basic math, start with the return signal level at the modem, subtract the loss of the cable footage, splitters, DC's and taps, what you have left is that modems input level to your amp or LE. If you have a loss that is too high you need to figure out which piece of cable or equipment is causing it. If the math works out close to spec and you still can't make levels, there is either too much cable (distance) or equipment between the modem and the amp. A house with cascaded splitters will give you hell, try to take the modem line off the first splitter if possible or run a new line directly to the modem so you can.
