To the scientist, Ultra-High Ere
quency (UHF) means a section of
the radio spectrum. Another name
for the spectrum is radio air waves.
The air waves, of course, belong
to the people, and it is the job of
government agency to divide
among various private and govern
ment services wireless channels in
which to transmit information cleo
ironically.
The services to which the gov
eminent entrusts the public's air
waves include police radio, tele-
vision Tin the Very High Frequen-
cies), FM broadcasts, civil radio,
amateur radio, government wire
less, maritime wireless, ship sta
tons, coastal stations, maritime
navigation, general navigation,
radar, air navigation, airport con-
troll, industrial, scientific and medi-
cal wireless devices.
Fixed Channels
Each of the services has fixed
"channels" in the air waves and
cannot intrude upon its sister serv-
ices. With television, the number of
channels used today is not suffi-
cient to carry video signals to every
part of the nation.
Since the inception of CONNER
cial TV, tie lie is have been
beamed over IL channels in the rel
atively limited Very High Ere
quency section of the air waves, but
with new stations mushrooming
around the country, the Federal
Communications Commission de-
cided it had better call halt be-
fore TV signals began humping into
each other. Its decision was prompt
ed by the realization that two tele-
vision signals transmitted over the
same channel within range of one
another will collide and thus hash

The one untapped section of the
spectrum which promised plenty Of
room was UHF. This was the area
in which scientists and engineers of
the Radio Corporation of America
began looking for new television
channels.

looking into it,, according to OBJ.

engineer of the National Broadcast

Equipment Developed
Out of years of expensive re-
search and field tests, equipment
was developed which made UHF

1t was found that UHF station,
properly situated and properly op-
Grated could furnish home viewers
a picture that equalled in clarity
and definition the standard VHF
| picture.
1t was found that present hone
| television sets could receive UHF
| telecasts through the addition of a
| simple tuner and that receivers
could be built to receive both UHF
and VHF telecasts.
1t was found that the enlistment
of 70 new UHF channels for tele-
vision would permit an orderly ex-
nansion of VHF service without
fear of station conflict.
These findings provided the bass
