I have Dish DVR-522(Dual Receiver). May "Satellite 2" signal, which runs through the existing coax lines in my house and is how I receive my signal on tv's not directly hooked to receiver, is fuzzy. I'm sure it is because I have older coax and I'm pretty sure there are splitters all along my existing lines. Is there anyway to fix this since re-running new coax and even taking out the splitters is almost impossible. Please Help.
