Remember when the countryside was littered with those freestanding
AT&T microwave towers, which formed the backbone of the U.S. long
distance telephone service?
Only a handful are left, and most of them are covered with cellular
telephone antennas.
Big sticks can also be LOWERED to heights that are appropriate for
the SFN infrastructure needed for each market, and in some markets,
the primary transmitter may well be on a big stick. The real issue
here is how to redeploy existing transmission assets in a modern DTV
infrastructure that will maximize coverage providing reliable, hassle
free reception.

This is absurd. Not even close to being true.

1. Y9ou don't need 50 little sticks to cover ANY U.S. market.4-5
mains are typically adequate, with repeaters out in the suburbs.
And getting the signals to these transmitters is not difficult or
expensive. That was the OLD argument used to blow COFDM out of the
water in the early '90s. That was BEFORE we spent billions deploying
fiber everywhere. Now the only problem is what to carry on all of
these unused fibers. We can also use other distribution networks
including satellite and microwave as needed for each network.
