I just switched from Directv back to Dish Network, and I am befuddled about the way the install was done. With Directv I installed a 4x8 multiswitch to run all my televisions. Well, I am currently only using 2 televisions so when switching to Dish I only ordered the DRV-625 which is a dual tuner receiver that can run two tv's.
Now, to my question. I was always under the impression that you had to run coax from the satellite to the receiver without splitting. However, when installing the Dish dual tuner receiver the installer took one of the cables from the satellite and ran it into a splitter which fed the two cables running to the two tuners on the receiver, and also to the cable that runs directly to the 2nd television. How can this work? Is this some sort of special splitter? With Directv I ran two separate cables from the multiswitch all the way to the dual tuner receiver. Is there a difference between running to two separate receivers vs two tuners on the same receiver that allows you to use a split signal? Perhaps the same would have worked for Directv and I just didn't know it.
Also, he is completely bypassing the multiswitch that I put in. I'm not sure how the dual tv receiver passes the signal to the 2nd television (somehow it goes over an "on-air" frequency through the coax). I am assuming that the multiswitch would interfere with this pass through, and that is why he bypassed it. Is this correct?
