I have direct t.v. service in my home & want to take one of my recievers and use it temp. in my sons collage room. Their is a dish not being used on his building and was told o.k. to use, when I connect the reciever, I only get searching for satelite signal. I Direct t.v. wants an addtl' $55.00 a month ! I can use it on my R.V w/o any adtl' cost - Anyone know how to deal with this ?
