]itech YOUR ATTENTION TO
THE COLLINS 20C ONE-KILOWATT BROADCAST TRANSMITTER
REASONABLE COST
The price of the 20C bears a sensible
relation to the actual cost of design and
manufacture.
HIGH FIDELITY.
Collins broadcast equipment has established a unique reputation for faithful transmission. The frequency response of the 20C is uniform within plus or minus 1.5 decibels from 30 to 1 0,000 c.p.s. Total r.m.s. harmonic content is less than 5 per cent of the fundamental at 95 per cent modulation.
QUIET CARRIER
Carrier noise is held at least 60 decibels
below program level by generous circuit
design and without resorting to "hum
bucking."
RELIABILITY
All components are oversized and adequately protected by overload devices.
SIMPLICITY OF INSTALLATION
The 20C operates from single phase current which is readily obtainable. There are no external auxiliaries and all wiring including transmission line is carried through standard conduit.
EXCELLENT CONSTRUCTION
The use of the very best materials and
the most skillful mechanical design gives
a fine appearance inside and out.
NEW CIRCUITS
Low loss inductive neutralization and a new high stability oscillator are among the many important electrical features.
