I have a A9 and a H20 install scheduled for tomorrow. I confirmed with the installer that they were bringing the right equipment. They also stated that they would be bringing a multiswitch. I have a few questions regarding the multiswitch since I didn't plan for it. 1. Can the multiswitch be installed on the outside of the house exposed to the weather? 2. Can the multiswitch be grounded with the dish and eliminate the need for the coax to be connected to a ground bar before entering the house?
