The pre-amp is a Winegard LNA-200 Boost XT Outdoor Digital TV Antenna Preamplifier (

I have about 100' of RG6 cable run. I ran another segment of RG6 quad shield to the back of the DLP TV because I could get nothing on the RG59 segment on either TV. I know that cable works because we used to get our cable TV on it.
I have 2 splitters but neither are hooked up. One is an Antronix CMC3002H and the other is a CMC3004H. I could just barely get a signal out of the 2-way.
The channels I got were WCAU 10.1 (had the best picture) and I think WPPX-DT and WACP. I'm at work at the moment and can't check.
Here is the setup:
Antenna with LNA-200 mounted on the mast with about 30' of RG6 into the pre-amp. From there about 70' of cable to the distribution box and back to the TV. I can get a much better picture with a shorter cable from the distribution box. The extra 30 or so feet really diminish the picture.
Both TVs are Samsung. The DLP is an HL-S5687W made in Nov 2006 (I don't think it has a QAM tuner, whatever that is, but I was able to get 45 channels on it before so I don't think I need a digital converter) and the LCD is a LNT3242HX/XAA. The DLP seems to be much more sensitive to longer cable runs than the LCD (probably because the LCD is a year or two newer).
