The antenna is about 8-10" square
The guys who installed it told me there was 5 masts in the local area. They told me roughly where two of them were located. I just used google maps to find the distance as the crow flies, and one mast was 1.57 miles away, the other was 2.4 miles away.
They were unable to receive a signal from my local mast, probably due to the line of sight. My aerial is definitely pointing to the direction of the mast that is 2.4 miles away.
There is only one cable connected. I just went outside to take a pic for you and i noticed that the cable is just laying on the roof. I wont complain, but may need to if it gets blown off. Also the aerial is attached to the tv aerial. T&K brackets would have been better, but again, it works.

I am currently impressed. I just need to be a bit more careful with my downloads. As long as i download stuff overnight, i am hoping that i will be ok on my current package. I need to be a bit careful during business hours.
