[TowerTalk] AN Wireless HD tower installation advice needed

[David Gilbert]

That's not really very practical in the case of the AN Wireless 
towers.   The top of the base only extends a few inches above the 
foundation, and it needs to be suspended above the dirt at the bottom of 
the hole.  if you pre-attach the first section of tower you have a 
pretty heavy combination to deal with.   Most people assemble the base 
inside the hole, and getting a tower section mounted on it before the 
concrete was poured would be a tricky and difficult proposition at best.
