Unless I can catch the Hispasat signal under the trees, that will be impossible for me, because a barrier of leafy trees covers the vision towards the east...
Elevation for hispasat: only 10 degrees... Do I need bigger clear for signal captation or only need a clear of my dish size?
you need a clear line of site and since its that low (I'm in the same boat...9.4 elevation) you pretty much need a straight shot. Remember the dish "sees" about 22-25 degrees above where the LNB looks. So even though the dish is straight it's seeing 22-25 degrees higher. Offset dishes do that. Prime focus is legit
38 degrees on a prime focus looks like 60 on a offset
