OK. So my neighbor has just about completed an addition to his house. Since the addition, I notice that my Signal Strength on the 99 Sat is appalling. How can I work around this. My problem is that the 99 and the 101 goes into the same port on the HD Slimline 3 LNBs. How can I work around this? I have tried relocating the dish but the new location affects both 103 and 101. So to summarize... One location gives a good 99 but the other gives a better 103 and 101. Can I install the second lnb and use the SWM? What do I need for this? Thanks in advance.
