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: http://www.dxengineering.com/parts/dxe-cgb-150
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
