Usually with a DMX self supporting tower, you need plenty of concrete. Usually a block of at least 3' x 3' x 3' is required. However in my case I am mounting my "hybrid" tower both bracketed to my house and spiked with a base hinge (described in previous post). I decided to lock in my spikes from any shifting or torsional forces with a base cap, a slab 3' x 3' x 4". This required 6 bags of 30kg cement. After the obligatory kids hand prints and a couple of hours of sweat, considered it "locked" in. Notice the plumb bob still smack in the middle. It is strung down the middle of the 3 upright sections. The wooden post at the back is for mounting the winch, my next part of the project.
