To start off, this URL takes you to the Engenious ENH user forum.
Outdoor (ENH and EnStation series) - www.engeniusforum.com
Good spot to browse, or for questions not answered here.
UPDATE*** Link no longer works, as they changed their website and the old posts are gone.

Once the snow leaves I'll try and get some photos of my antenna mast/mount and post here.
