I need to run some rg6 coax from my house to a tree then over a road to a post down on my beach to get the line of sight shot to the correct satellite to get my locals in HD. The run should be less than 200 ft. I need to know if there is a specific type of rg6 that I should use for this overhead application. If anyone has done a similar run what is a max length that you can run before you need to boost the signal and what type of cable should be used to hold up the weight of the cable plus any snow or ice?
