I recently had a technician come out to install a HR-20 because I thought they had opened it up to the OTA channels. He told me that OTA channels are not activated in Pennsylvania. This is opposite of what I was told over the phone by the person that took my order. What is the truth?? He wanted to intall the dish on my roof with 10 lag bolts, which I refused. I installed a chain-link fence poll in 2 feet of cement which makes it 6 feet above the ground and open to the southern sky. Does anyone have problems with wind flexing the pole with the dish being 33 x 28??
