Thanks for pulling that item up. The long-lines website is a cool place.
There are a few other sites that document the early coax and microwave
paths.
IIRC my past reading... some of the paths were in part military related...
and had some funding (and protection specs) from the federal government.
The AUTOVON system comes to mind. A little googling will bring them up.
Reading them causes me to see
Back to TV uses, based on the linked article's rate of $35 per month per
airline mile, a circuit from NYC to LA cost around $86,870 a month for eight
consecutive hours of transmission per day, and additional consecutive hours
at $2 per hour per month would cost $4,964 per month.
Not exactly chump change back in 1948... and not chump change today,
either.
Had to chuckle when noting from the attached map that back in 1948, where
I live—Marysville—was part of the coax line from Sacramento to Portland
(wonder whether the SP railroad tracks were used?) while other parts of the
state... notably LA to SF didn't have that luxury.
It'd be interesting to discover whether any of the old coax is still in
place and/or in use... and what TV signals were carried at any time. North of
here, here were (and are) CBS affiliates in Chico and Medford.

At one time, the Marysville Central office had the old "horn" type
microwave antennas atop a tower.
When Ma Bell and the Baby Bells were broken up (cue Neil Sedaka) the
antennas were removed and the tower was bare for a number of years.
There's now a parabolic dish on the tower. Can't recall where it points.
