I'm going to relocate my SL3 from the roof in the front of the house to the back of the house strictly for asthetic reasons. My neighbors trees fell down in a wind storm witch opened up new dish mounting locations for me. I have 3 routes to choose from each with varying amounts of work to get the coax from the dish to the Zinwell WB68 switch wich is located in the basement. The longest route would use 50' of coax and the shortest would use maybe 30'. With short runs like these and using solid copper cable does the extra 20' of cable length really matter ? BTW, The length of cable from the Zinwell to the DVR's is about 4'.
