Mine came in the mail today and I am planning to install it next weekend. I did open the box and was going to post some questions also. No instructions either.
1. I am not at my dish right now, but I do believe my feedhorn is a Chapparel and that has the bolt set the focal distance. I was told to remove the bolt and take the assembly out and use my existing scaler ring. No problem. If I use the scaler ring that came with the BSC421 the LNBF will not be centered in the scaler and then it will not be centered in the dish. I took a picture of it. Is this normal?
2. Prior to removing the above I am going to measure the distance from the throat to the center of the dish so that the LNB when mounted will be the same.
3. Is there a trick to getting the polarity correct? My plan is to bring my Uniden receiver out to the dish / w TV and hook up the LNBF outside and tune it to TBS and TNT on Galaxy14. If I get those to work, that means to polarity is correct.
