The Tower

This 100' tower tilts over at the base so I can work on the antennas from the ground. Click here to see tower lowering.

It is all aluminum and has a motorized steel folding plate, all crafted by Heights Tower Systems, Inc. of Pensacola, Florida.

There are no guy wires. The anchor rods are sunken into a concrete block that measures 6'X6' and is 7 feet deep.

The antenna is a Force-12 Model C3 at 105 feet. There is also a 6m beam at 95 feet.

The 6m beam has since been replaced with a 27' dipole and a Smartuner.

The tower is engineered to withstand winds of 100 mph but the strongest wind recorded so far at my QTH has been 67 mph. The legs are 34 inches apart at the base and taper to 18 inches at the top.

This is the motorized folding plate with the tower fully upright. The hinge is on the left; the motor on the right.
There is a 1.25" worm gear and gimble that causes the tower to tilt as the motor turns.

It takes about 20 minutes for the whole operation to complete. Click here to see more about tower lowering.

Now this is the way to dig a hole. Get your contractor to rent a small backhoe, sit back and watch as he does the work. Donation of a case of beer helps, too.

Here I am tying off the rebar cage and the anchor rods the day before the concrete is going to be poured.

It took 6 yards and cost about $750 for the concrete. When we built our house I had the contractor dig the hole for me with a back hoe.

The tower worked perfectly until I goofed up. [See
