Hi everyone! I would like to upgrade to DISH 500 and keep my current DISH 300 so I can receive programming from the 61.5 satellite location. However, it was my father who originally installed my current Dish Network system about 6 years ago and he had to put the cable through numerous walls in our house. Therefore, I was concerned that the installer will not be able to hook up the DISH 500 to the receiver if he requires access to the cable running indoors since my father would most likely not be home during the time the installer would come and my father is the only one that knows where exactly the cable is. After reading some of the installation guides on dishnetwork.com, I realized that the switch can be installed outdoors. Therefore, the only solution that I can think of is if it is possible for the installer to disconnect the cable from the DISH 300 and reconnect it to the switch instead and connect 2 new cables to each dish. Does anyone know if this is possible or if the installer will require access to the indoor cable? Currently the cable comes out from the inside through a hole drilled in the basement and it goes up the side of the chimney to where our dish is located. I only have one receiver and I think it's a JVC 3000 but I'm not 100% sure.
