That Ampegon Antenna has to be in the $200 - $300K range.
I suggest that it might cost more than $300K US.
$150k US might cover the labour cost of two engineers (one electrical and one mechanical) coming from Switzerland to install along with the labour of the team of construction crew and riggers who will actually pour the concrete, install the motors, assemble, put the thing up and ensure mechanical functionality. Maybe the riggers will come from Switzerland, maybe they won't.
Not covered by the above: any NRE, cost of shipment, cost of materials, cost of partial assembly in Switzerland, profit margin (which won't be less than 50%).
