Ditched the expensive satellite cable service and have gone to wifi streaming. Then I bought the cheap amplified indoor HD flat panel HD digital TV antenna for local stations. The indoor antenna picks up 69 stations BUT I have to move it around to get one I frequently watch. Some days I must have the smart TV search out the available stations again. So I'm now thinking I should buy and outdoor antenna, take down the unused dish, use the dish arm to mount the antenna, connect into the existing house coaxial cable system. The questions here are what antenna to buy. I'm thinking a Channel Master omni-direction unit about $170 from Amazon. Then it seems I should buy an antenna amplifier as well. Anyone else face this? Have experience?
