Im temporarily living in our travel trailer. I was able to locate and lock into 82, but only had access to limited channels. I was hooked directly into my in-laws dish which is set up to 91 with full access. Now that I moved the trailer, I have to use my own dish. Is it common to have limited channels with 82? I have a satfinder, but no gps or compass to use for direction. Any suggestions are appreciated.
