Hi. I would like add HD service to my home. D* gave me a free HR20 and setup installation for a day last week. I knew going into the installation that the installer would need to get creative because of trees, but I did not have enough knowledge at the time (had not read here enough!) to offer suggestions. As you can guess, the installer was here less than 5 minutes before he said, "Sorry bud. No line of sight." I asked about using multiple dishes and he just gave me a weird look dismissing the idea completely. He pretty much said HD was impossible because he couldn't get all 5 on one dish and that a second opinion wouldn't matter. I reluctantly said ok and he canceled the order. Disheartened, but not ready to quit, I googled trees and HD and found a wonderful thread here on DBStalk started by litzdog (you seem to really know your stuff!) regarding the use of multiple dishes to acquire HD. Litzdog ended up using 2 AT9 dishes to get all 5 sats and provided some wonderful information about other configurations that would not work along the way. I was lucky enough to find 2 AT9 dishes on ebay and placed the order for them. They are to arrive tomorrow (Monday, Aug. 13). Once I found these dishes, I called D* and told them I wanted a second opinion. The installer should be out Tuesday. However, now I think it would be best to just do it myself. I don't want t obe charged for a special installation and frankly, I don't trust the installer to do a good job. So, I have a bunch of questions about doing this myself and questions about getting money from D* for doing it myself. 1. Since I bought 2 AT9 dishes and D* was going to give my an AUS9 dish, am I entitled to a credit for one of the AT9 dishes? 2. Installation and testing signal strength: I currently have a single 18" dish and 2 D11 receivers. I will replace the 18" dish with one AT9 dish (110 and 119 lnbs removed) to acquire the 99,101, and 103 sats. The other AT9 dish will be approximately 60 feet away and *should* pick up the 110 and 119 sats. Here are my questions: a: I align both dishes to point at the 101 sat, right? b: How can I test the signal strength of 101 dish using my current D11 receiver? c: Will my current D11 receiver allow me to test the signal strength of the 99 and 103 sats? If so, how? d: How do I test the signal strength of the 119 sat using my D11 receiver? Do I test at the second dish position before running the cables to the main dish or do I test at the main dish? As you can probably tell, I do not have a signal meter and do not want to purchase one, I want to use my current receiver to test all signal strengths. The receiver currently is setup for a single dish, will this receiver pickup signals from multiple dishes? If so, how do I setup it up to do so? I beleive that is all for now. If you guys know of something I am forgetting, please bring it up. Thanks so much for your help!
