Hi Texasdiver & Neutron,
Thanks for the ideas.
I do have a plumb mast if the included bubble is correct. I'll verify with a machinists level.
I doubt that tree limbs are blocking the view. The dish is ~ 20' high, and the closest tree ~ 60' is 200' distant, and on lower ground, so given the 40-degree elevation angle, I think it would take some monster tree to be blocking the view.
Regarding the coax. It's new CommScope F660BVV (RG-6). Most of the run inside the attic is through conduit with nothing else in it, and it was an easy pull, so I'm sure there was no damage to the cables (4). F-connections are solid; I bought the industrial crimping tool at Radio Shack. I covered the outside connectors with StarBrite liquid tape. Anyway, I'm only using two of the cables, and the tests for the (B) satellite that I did get transponders for showed a high of 92, and a low of 84 for both of those cables. I do not know what to expect, but to me, that proved that there is no major problem on the cables or connectors I'm using. The other two cables are connected to the multiswitch at the LNB, and I just checked the unterminated ends of those for possible connection between shield and center, and they are fine.
I will contact DirecTV and give them my Lat/Lon to see if I can get another set of aiming parameters. Thanks for that idea.
