Coaxial-cable line-tuning equipment

THE ADVANTAGE of using low-loss cable in conjunction with power-line carrier equipment has been recognized for some years. The use of this cable has made it possible to locate the carrier transmitter-receiver in the most convenient place rather than out near the capacitor which couples the carrier signal to the power line. Coaxial-cable connections have resulted in much more flexible carrier installations than was possible before this type of cable was used.
