Dish sent a guy out to add 2nd dish for 61.5, he hung a DP21 switch on the pole and ran coax from 2nd dish over to switch, ran coax from first dish to switch then in to house. Every thing worked fine but coax was ran across yard so I decide to run coax from 2nd dish in to the house and hook up switch in the house out of the weather but now it wont work, it wont read the birds. What's up with that ?? Does switch have to be mounted so many feet from receiver or ??
