DO RUN THE GROUND THROUGH THE CONCRETE!  Take a look at the information on
this site first though.  You may be glad you did.

Hi Dave,

I have a 48' tall, tapered, self-supporting "Delhi"-brand tower --- 6
sections at 8' long each.

The prescribed / manufacturer's recommendation is to bolt a 3' straight
formed extention at the base of each leg (total of 3), & to "suspend" these
(a temporary wooden "cradle" will do admirably, as the cement sets) in a
hole dug 4' square, & 4-1/2' deep --- the cement is to come but a few inches
below the bottom legs of the actual tower section.

Oh yes --- the bottom 1' of the square hole is to be "belled" outward a
foot, or so.

The documentation says this is good for heights of up to 64', or so...I've
never gone beyond 48', & have never, EVER had an ounce of trouble in the two
locations that I've had my tower up.

BTW, the top of the tower as an old Cornell-Dubelier AR-44 rotator, & a
3-element Hy-Gain TH3 MkIII triband yagi...

Use "industrial"-grade coarse cement, & do NOT run any ground leads through
the block itself!
