I think everyone agrees the EL, AZ, and Skew change as you move around the country. The values for a specific location differ depending on the Antenna/LNB you are using. The numbers for a SL3 (looking at 99, 101, and 103) are different from the numbers for a 3 LNB (using 101, 110 and 119) in the same location. Be sure you are comparing apples to apples when comparing AZ, EL, and Skew from Dishpointer v. DirecTV's website v. entering a zipcode into the receiver.
As the OP has a HD receiver, he most likely is using a SL3 LNB to get his signals. HD is on 99 and 103. the 101 sat provides non-HD signals, some music and misc channels. The 101 Sat is an old style one that can be aligned and peaked using a cheap "squealer" meter. The 99 and 103 Sats use much newer and more sophisticated technology and require an expensive special purpose meter to tune them in. But it doesn't matter. Use a good tripod (TV4RV.com is a good source), get it plumb, set the EL and Skew correctly, and then tune to, and peak, the 101 Sat using whatever meter you have (cheap to expensive). Because 99 and 103 are *SO* close to 101, they too will be plenty strong to be useable. No need to employ a Birddog (or alternative) to handle their special signals.
I can have my SL3 antenna setup within 10 minutes from start to finish using just the 101 Sat and then start watching HD stations.
