The idea is that I can inspect the ground connection. I also didn't want to
have things interfere with my lawn mower. I kept the wires as close to the
rod as possible, thereby minimizing the inductance. Right? Time will tell.
I have a good amount of old fencing laying around and decided to add some
"heavy fill" when I refilled the hole. It is more there to stabilize the
ground. You may note that the only concrete is the three "pillars" around the
anchor irons. There is no access for a cement truck and this was my method
to make a base. Most on the momentum is taken up by the ~4' x 6' granite
slab on the bottom of the hole.
I used the "falling derrick" to raise the tower. You can see the derrick
laying on the tower in one of the pictures. One guy wire was attached to the
derrick. I added some extra wire to the guy and used a couple of
"come-alongs" to pull the tower up. A motorized winch would have made it
faster but I
had the time. The "come-alongs" were attached the wire with "dead-ends"
the same type as I used to fastened the guys to the anchors.
All went very well and I had no major problems during the rection.

I would have connected the ground wires with the last inches running
parallel to the ground rod downwards instead of upwards. All curves create
impedance. Think of your ground conductors route as a road where a high speed
car needs soft curves and not sharp bends. A minor detail, anyway, you can
leave it like that.
What are those grids you set up horizontally over the concrete? Is it
copper or steel reinforcement bars? If it is rebars for the concrete, there
should be a minimum of three inches of concrete between the soil and the iron,
to protect it from corrosion.
Would have been nice to see pics of the structure that routed the pulling
wire in a high angle to erect the tower.
Neat and clean method of installation. Cool.
