Is there any difference with the two inputs? Do they help with Dish Alignment or do they serve two different purposes.

I found my lat/long coordinance last night and the Dish Alignment specs are a couple of numbers off their initial set up.

Just curious

lat/long is exact location, zip code is a large area.

Gracias!!!!!!!!!!

What made me curious about the Lat/Long coordinance is that it's almost the exact settings for my R10 Tivo.

The settings for my HR21-100 are off by 10 to 12 degrees, but I'm also taking into consideration how precise the Slimline 5 LNB has to be with regards to alignment.

The alignment for the 5 LNB dish must be very precise for the new Ka band satellites. The dish alignment procedure uses the Zip code settings as a starting point for the alignment process.

Ok, well a Tech definitely needs to come back out and re-align this dish because I do not remember him ever using lat/long adjustments. My 99 and 103 numbers are very low, in the 60s.

The numbers from the receiver include the correction for magnetic north deviation from true north. Where I live that is around 20 degrees.

The R10 doesn't have a 5 LNB option, but the single LNB numbers should be comparable (the 3 LNB dish is pointed differently, since it is centered on 110 instead of 101).

In any case, these are just starting numbers and you need to adjust the alignment based on signal strength.

OK just did an alignment and now my 103 transponders are in the hi 70s and low 80s.

Update: Without loosing strong signal strength to 101,110, and 119, I managed to get 103c to the mid to high 80s. Tilt was set for 61 and I now have it at 70.

Not quite as simple as that. You'll need degrees, minutes, and seconds to get a good approximation using lat/long. Some zip codes are pretty small -- mine is 5 blocks by 20 blocks, about 1/2 mile by 2 miles.

Either way, it's just a good starting point for aligning your dish, as others have pointed out.

The dish itself is not exactly a precise scientific instrument. It's mass produced pressed and stamped sheet metal. Take the setting lightly, say plus or minus two degrees, maybe. The settings are just designed to get you pointed in the right direction with a good chance of hiting the 101W sat on the first try. Preadjust dish on the ground, mount it on the mast, point in direction more or less, swing it slowly on 10-15 degrees arc, and bingo. Now do tilt for 119W, then fine adjustment of Ka signal, and you're done. (It actually is almost this easy if your mast is plumb.)
