I am moving my DTV system from a brick and mortar house to our motor home. I intend on keeping the 5 lnb dish from the house and the power inserter. However, for varying reasons, I wanted a new splitter. The current splitter in the house is a sws4wb-wnc which is what I ordered from Amazon, fullfilled by Reider Electronics. What they sent is a mdusp4r0-09. My questions are: Is there any difference in the functionality of these two splitters? Does one wire them the same way? Is there a significant cost and or quality difference? If they will work the same I will go ahead and install this new one, the MDU...., and not worry about any cost difference, although it appears they substituted a $6 item for a $14 item. Any thoughts or advice? Thanks.
