Just to put things into perspective... An AM station on 1170KHz... is
operating on a frequency with a 1/4 wavelength of approx 200 feet.
So, for an FCC approved 1//4 wave vertical antenna... you have a 200 foot
tower...
Like Rohn 55... twenty 10 foot sections @ approx $350 each...
120 radials at 200 feet each = 24,000 feet @ approx $0.30/ft
Tower sections approx $7,000
Radial wire approx $7,200
Then add: base insulator, concrete for antenna base and guy
anchors, rebar, guy wire, guy wire strain insulators, and installation!!
A bit of money...
Just for grins... check out this video which talks about elevated radials,
which were mentioned last night!
Note that for our 200 foot vertical radiator, if we go to elevated radials,
we would probably add two tower sections, approx $700... but we
only need 1,200 foot of radial wire, at a cost of approx $360!! A savings
of approx $6,800.
