I watch very little TV and have no "commercial" television service
, "air", cable or sat at home. I do have a powered antenna mounted to my starboard spreader and it provides great reception! It is made by Shakespeare, though I am not sure the exact model.
It seems to be unaffected by any of the boats motion. Regardless which antenna you go with, you will most likely want to mount it high. A few of my dock
mates have theirs mounted on their Bimini
and they all say that they are not happy with the reception.
