One way to think of a satellite transponder is like a big fat radio channel transmitter carrying lots of TV channels. For example, Transponder 1 of DirecTV's 101-deg W (Satellite A) might have a dozen different standard definition TV channels carried on it. Some transponders, such as Transponder 1, are nationwide-beams and cover the entire US. Some transponders, such as Transponder 4, are spot-beams aimed at a small portion of the country. That's why the signal levels vary from one transponder to the next.

When you are watching tv, the DTV receiver selects which transponder it needs to get the channel you are watching. You have no control at all over which transponder is selected (other than selecting a channel to watch).
Other than aligning a dish, or troubleshooting if you are having problems, there is really no need to look at transponder signal strength.

But, don't pick one of the spot beam TPs. Some of these can be 0, very low or 100. On sat 101 they are 4, 12, 18, 20, 26, & 28.
If you gonna fine tune your dish, use weakiest tpn for that.
