We are trying to connect a dish network system to our rv. We have a 311 receiver and a dish 500 with the SW21 switches. First, is this ok or do the switches have to be dish pro switches? I was confused reading some posts. When we tried to hook it up we received a signal and thought everything was fine (after receiving a message about too few satellites after running check switch) then we came back a few minutes later and there is no signal and the check switch said something about a bad switch. Sorry that I don't have specifics but I wasn't writing this down and this is information that I am pulling out of my husband! My first question is if I have all the correct equipment such as the switches. Also, we will have about 65 feet of cable from the dish to the receiver. Are the in line amplifiers to boost our signal any good? Thanks for any of your information to try to get us started.
