My dish is pointed at 100% on 119 (used a signal meter for it), but my signal is low for 118.7. How can I get a stronger signal for 118.7? Should I add another power inserter? Should I run separate lines to TV1 and TV2 instead of using a splitter right by the box? Stations keep flashing on and off and it sucks watching the CBB games like this. I am using a VIP622 with a 1000+ dish and DPP44 switch with the power inserter. Thanks.
