Cool! I for one, really didn't like the outdoor pipe mount. It was tough for us to get mounted, but maybe we just got one with the tolerances a little low or something. The indoor mounts are fantastic though.
Nothing really particular was tough with the pole mount - in fact I think it was the most easy mount option for me and my needs. I did use smaller hose clamps - since the top rail pipe mast was so small. BTW the top-rail of a chain link fence makes for a great mast and is low cost - plus protected from the weather. More photos of the install are in in my Flickr Gallery
