American tower owns a number of sites along I44 that used to have cellular
carriers on them, but do to sales of the companies, the sites were pulled. Most
of the time they just sawzalled the hardline at the building, pulled the
electrical, and moved the building. The sites now sit vacant, waiting for
tenants.
The coax is NOT waveguide - its coax. Waveguide would not last a week
swaying in the wind, the copper thiefs would have it down and stripped.
Waveguide is hollow. Just a hollow tube - if it is coated with black
insulation it is normally eliptical while some sites like former AT&T sites
had a rectangular waveguide - and a round waveguide, without insulation.
Coax has a center conductor - waveguide does not.
