I have a customer in a situation where he would need four tuners. I initially set him up with (2) 311's and (2) 211's. I used the 1000.2 antennae, but with the W bracket and single dp lnbs that led to a dp 34 switch. One of the recievers went out and a tech came to replace the reciever, but also replaced the single lnbs with the integrated 1000.2 lnb. Now one of the 311 recievers keeps getting a switch error. Is the problem the dp34 & integrated 1000.2 lnb? What is the best solution?
