Still deliberating/procrastinating on my upgrade/dish relocating project. Really want to relocate the (1000.2 western arc upgrade) dish to the attic and "shoot the birds" through a west-facing attic window. Had read somewhere a while back some discussion about relative transparency of different materials (or lack of) to sat signal, and seems like clear plastic "plexiglass" type was mentioned as a better, or at least acceptable, material to gather signal through.
Since that attic window could use some rehab anyway, I'm considering rebuilding it using clear acrylic plexiglass to accommodate the dish. To that end I did a little experiment------- pulled up the signal strength graphic on the kitchen tv, dragged a ladder to the present 500 mounting site, and went up and put a piece of the aforementioned plexiglass in front of the dish (while the wife monitored the signal strength). With a very clear early afternoon sky the signal strength on 119 hovered at 80-81 until I put the plastic in front of it, at which time it dropped to a solid 70, a ten point or more drop in strength.
Was wondering if anyone might have a sense of whether or not starting out with a ss of 70 on 119 under essentially ideal conditions would be enough to expect reasonable pq for the western arc array. Would also appreciate any other suggestions as to any better window glazing material for my purpose.
It can be assumed that the dish will get a full view of the sky, I will see to that. I am located in the mid-Atlantic region about as as far east as one can get, but due to large trees the eastern arc is not feasible.
All input is greatly appreciated.
