    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'.

    You'll be fine. Length only becomes an issue when you start approaching the 150' mark.

    If you do not have any non-swm capable receivers, consider replacing the SL3 with a SL3-SWM LNB and replacing the multiswitch with a splitter. The cost of those two items would about equal 3 extra runs of coax from the new dish location, and would put you in the ready for the new Multiroom video, and other goodies coming down the line from DirecTv...Just an idea.

    Well, you don't need SWM for the multiroom video feature. You need SWM to be able to run ethernet over the coax when it becomes available. The MRV just needs a good ethernet connection, no matter how it is supplied.
