http://www.thepittsfieldinn.com/Bill/ gives some great detail on loop
construction.
mine is 40ft up, 200ft along, 40ft down and returns about 6ft back. The connections are in a small box - mine has a 1nF cap (shd be 2) in series with the inner of the thin coax to one side of the loop, other side of the loop is connected to the outer of the coax, and the resonating cap to bring it to 137Khz across the loop (and defacto inner to outer of coax) is around 13.5nF its cheap - easyish and I used a 2.5 pound weight to throw it up the silver birch tree (Im in weight training!)
