I have a 2 hopper/3 joey setup. On both hoppers, when I need to use tuner 3, I get a lost signal message. The other tuners still work and have signal on all channels. Is there anything I can do to boost the signal so all 3 tuners will work? Prior to upgrading to the hopper I had 4 dual tuner receivers with a dpp44 switch. The installer removed the dpp44 and took it with him. Would having the dpp44 help my signal?
