While your technical arguments are correct, they
could be interpreted to show that UHF TV an incredible waste
of spectrum space! With a typical stations consuming 7 channels
(it's own plus 3 guard channels), that station uses 42 MHz of spectrum.
That is more spectrum than the ENTIRE HF BAND - just so someone can watch
a few reruns and a TV broadcaster can reap bucks primarily by having
acquired a public resource (the spectrum) for his own private, government
protected, business! So... save us your sanctimonious flames! Some day,
the public will become aware of the convenience and safety that they
could get if these frequencies were opened up to mobile telephone, messaging,
remote control, packet radio, etc! Meanwhile, DBS and cable will remove the
EXCUSE for allocating this precious natural resource to reruns of I love
lucy! Just how many stations does it take to properly serve an area? How
about an urban area with available cable? You call for the "NEED" for
HDTV. Need? To waste even more bandwidth???? How about using satellite?
Satellite, of course, uses just as much spectrum (or more). However, it
can happen on frequencies that are technically unsuitable for mobile
radio, such as K-band. (Try making a mobile antenna for K-band - you either
get an unacceptably small capture area or unacceptable directivity).
