Pictures from the week of 9/3. Check out the grounding strap and points at the bottom of the pole...The color at the bottom of the pole is a fire retardant.
More site work
Last week the ground system was laid and soldering was finished
Laying the ground system from earlier
The "paint" on the bottom of the poles is a fire retardant
copper straps to form ground system
The truck approaches....with overhead cables, and more
OK so Mark is excited the truck is here...can you tell by the pics?
And its Christmas!
Presents for the tower site...
ATU - (or the box at the bottom of the towers that interconnects the transmitter to the towers/poles) - for us non-engineers, where some of the magic happens.
A transmitter generates (in our case) 5000 watts of signal that is then connected to wire and run up a tower to "radiate" to your radio.
The signal runs through this box (ATU) before heading up the tower.
This is eventually where the ATU will rest
Work begins up high...as mentioned earlier, our new antenna system is a series of short poles interconnected with overhead cables to form a transmission antenna.
Workers begin the process of leveling the tops of the poles (with a chainsaw), and fitting each for the overhead cables
These poles are only about 60 feet in the air, compared to our current tower which is about 200 ft. Conventional AM antenna towers reach 350 or in some cases over 400 feet.
Work has begun drilling and fitting the connectors for the overhead cables and the guys to support the poles (wires running to the ground from the poles)
Support crew on the ground
Guy wires (the support cables that connect towers to the ground) are shown and add stability in the "opposite" direction of where the overhead cables will run.
The field is part of a working farm...MOO
Even more MOO
Eventually (soon) the poles, building and guys will have "protection" from inquisitive cows and the need to "rub" and "lick". The tower site does not pose any other risks to the farm, surrounding area or to the cows.
Lots of MOO!
Focus is key, I guess...
Again with the rubbing...moo
Someone always has to sign the concrete!
Overhead cable work begins. You see the ring at the top for connecting the other poles - central pole shown
Better view of the central pole - with wiring heading off to the other poles
The ATU frame and cabinet are just about ready to be placed on its foundation.
Once the station is live at this site, the inside of this box will be energized with 5000 watts of (daytime) power...you can almost hear Rush's voice in the box!

Better overhead shot of the cables
Placing the ATU
We're close! More to come - we have to put in power (SVEC), the building and oh yeah, a transmitter or two...
