TV Fool - Cutting the cable, need help

Hey guys, I am moving to a new house in a few weeks and have decided I am going to take the plunge and cancel my cable. I have always had cable, so I have absolutely no experience with antenna TV, but have been reading feverishly. I have done analysis on Antennaweb and TV fool, and seem to be getting very different answers, so I need some help.

My TV fool analysis is this http://www.tvfool.com/?option=com_wr...de6534b2b8e1f7

My plan is to put my antenna in the attic if at all possible, to avoid going out on the roof or seeing the antenna from outside. It is a 2300 sqft 2 story colonial, so I figure it will be roughly 25-30 feet up, under a roof with 2 layers of asphalt shingles.

As for wiring, I would like to run one line to my bedroom (basically across the attic and down through a wall) one to the basement (going to run straight down through 2 closets to the basement) and then once there, split 1 to a TV in the basement, one up through the floor to my office, and one up through the floor to my living room.

As for stations, the ones I really care about are the main broadcast channels, ABC NBC CBS Fox and PBS, from Rochester, which luckily are all in a line and all on the same tower. My confusion comes from TV fool saying a small indoor will get most of what I want, while Antennaweb says I need a violet catagory antenna, the biggest there is.

So my question is, what the heck do I need to hook up my system and reliably receive those channels when placed in my attic? What is the cheapest and simplest option that will get me what I need? What other parts (pre-amps, splitters) will I need as well? Recommend a good co-ax to run?

Thanks so much for your help guys, I really appreciate it. I'd be lost otherwise.
