After thinking about it for a while, I have concluded that the following must have occurred: Some time ago a crew from DirecTV replaced your old 3-LNB dish (which had an outboard multi-switch) with a 5-LNB dish (which has a built-in multi-switch), but they forgot to remove the old outboard switch. So now your system has two multi-switches. DirecTV systems are not supposed to have two multi-switches.
Here is what you should do:
1. Remove the outboard multi-switch, the thing that looks like a splitter that is 30 feet from your dish. You can discard it. DirecTV certainly has more of these obsolete devices than they will ever need.
2. Acquire an adapter that will connect together two cables. A Radio Shack 278

In-line amp
I returned the amp to the retailer and they are sending a replacement. I also have a request from MonsterCable to call them once installed so maybe they can troubleshoot the problem. I'll work on your recommendations in the meantime. Can't believe all the help, thanks a million.

Bypass splitter
I bypassed the splitter and the signal strength increased marginally (overall between 2 and 3 percent). The main difference is that most of the lower strength signals in the 60-69 range were increased to the 70s. I am going to see what happens if I connect directly to each of the other two lines (three go into the splitter). I am to get the new in-line amp in the next day or two and will try that as well. Thanks again.
