Finally placed an order for SG2100 and Winegard 30" dish on ebay last night. I was going to order via Sadoun, but they didn't have an SG2100... Anyhow, my house is basically Brick all the way up to the roof, and the house sits so that the slope of the Roof faces north and south. I'm going to mount the SG2100 to face south when I receive it. My question is how do you do that, making sure that it's secure and right on level to the south. I have some 2x4s, about 3 feet wide, stacked 2 high in 2 places on top of the roof that the previous owners used for securing Christmas Decorations. I am thinking I need to probably get up on the roof with a level, and move the 2x4s further up the slope to near the tip top of the house, mark where they will be with either charcoal, china marker or pastel colors or something, making sure that they are level and exactly running north/south and then take a level to them, figuring out exactly what 90 degrees straight up and down is and chop them down to that so that the slope off of those will be exactly up and down, and then re-attach them to the roof in the same exact spot that was marked with the level so the motor can be mounted directly to that instead of the slope of the roof. Is this the right way to go about this or can the motor be put on the roof directly and then somehow adjusted so that the skew of the roof's slope would be nullified inside of the mount's angle or something? I figure doing all of this with 2x4s will be much easier than trying to get drill bits for concrete and trying to mount to concrete somewhere that's already up and down. Yes, there are a place or two where eves are facing south but those are near the porch. I'm wanting to go further up the roof if I can since there's an apartment complex across the street. We sit on a hill. Our front porch faces south. Peeking out of attic windows that faces east/west, it looks like the base bottom of the roof is almost exactly level with the top of that apartment's roof... If I can get up a few more feet it'll probably give me a better line of site to the birds. I had an old 18" directv dish mounted on the poles on the porch the other day and it was pulling in 110 degrees satellite pretty good. I took it down and replaced it with another dish that someone gave me the other day that I think is a Dish 500 - it has two lnbs inside of one lnb head and indicates that one of them need to point to 110 and the other to 119. I haven't totally aimed it yet, but started to last night. I'm going to probably keep that up along with the new winegard on the roof when I get it up and going. I may (or may not?) also put the old dish (or one other old directv dish that someone gave me) somewhere on the roof and aim it at 91 degrees to get the freebie channels on nimiq... but that's just an open option at this point. I really just want to get the 30" going.
