My grandmother is interested in getting Sky Angel so I offered to take a look and see if she had a clear line of sight to 61.5, then do the install if everything was OK. What I saw was that anywhere on her roof the line of sight goes right through some power lines across the street. Has anyone experienced aiming through power lines? Will there be a problem? The only other option would be putting a tall mast on her roof. Going lower isn't possible due to the height of trees across the street and a low look angle here in the LA area (19 degrees).
