I have cable for internet and sat for TV. I used to install cable as a subcontractor, mainly hi-speed internet, but also TV.
If you have power your best bet is to have sat TV. I went out and determined the direction/angle on the sat dish, marked them down, then noted them in my "smart book". Should the dish shift, I can re-aim it and then call for tech support.
Having said that, I did stay with cable for the internet, only because DSL in my area is not so hot. What is odd, my power/cable/phone lines are underground. But I can go point to the spot they go back to arial - and if there is a good hurricane, I lose power.
I have two radios in the event I lose power. Pictures are not important, local news is. The past couple of hurricanes has proven that - local radio was 24/7 news that I needed.
