Can someone please help? I'm currently subscribed to Dish Network and have their DVR 522 receiver. I also have an FTA receiver (Sonicview SV-4000) as well. Now, I would like to add another FTA receiver but there isn't any port available on the Satellite. Currently there are two cables coming out of my satellite and each goes to separate receiver. My satellites are Dish 500 and one is pointing to 61.5, and the other one is pointing to 110 & 119 satellite. So now, what exactly do I need to add to pull another cable for my 3rd receiver? Your help is much appreciated.
