blstriker - got the antenna on ebay for right at $50 including shipping. Cushcraft 13.something yagi antenna.
ktwebb - on the other end of this link is a 14.something dbi cisco yagi antenna running into an AP in Point to MultiPoint bridging mode. That AP is wired to a university network running off T3.
as far as cabling goes, i don't plan on having any cable between the antenna and AP on my end. going to have a securely insulated weatherproof box with the AP in it attached directly through an adapter connector to the pigtail of the antenna. I will then run a single cat5e cable inside the building to my switch. the cat5 cable will be pushing PoE hence the ability to have it right there.
