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.

I think guying the tower section will keep it nice and stable. Pour
the first yard of concrete in slowly to avoid disturbing the base.
Attach several levels to the tower legs so that you can easily monitor
the plumb of the tower during the pour.

Subject: [TowerTalk] AN Wireless HD tower installation advice needed
I will be ordering an HD60 from AN Wireless on Monday for my windy
and lightning-prone ridge top WV location and have some questions
regarding installation:
1. It looks like the preferred way to support the base prior to
concrete is to rest the base on cinder blocks. Are there other tricks
needed to keep the base level and immobile during the actual concrete
pour? Perhaps I need to use rebar ties to fasten the tower base to
the rebar cage? I am paranoid about having the base shift during the
pour and creating a "leaning tower of Pisa" in my yard.
2. How did you run your feedline up the tower -- are there suitable
clamps available? The profile of the legs looks makes me think some
ingenuity will be needed.
3. Grounding coax at top of tower - Same tower leg profile
challenge. I have only found products that are suitable for tubular
shaped tower legs. So how do you securely bond the shield to the
tower leg of an AN Wireless tower? Example:

4. Grounding base of tower to ground field - I have 2/0 solid copper
that I need to connect to the tower legs at the base. Same tower leg
profile challenge. The tower is galvanized so I need some sort of
stainless steel plate to separate the galvanized tower from the
copper; and I need to figure out how to make a solid connection of
the ground wire to the tower legs. I have no idea how to make this
connection.
Thanks for any advice.MatKK1C
