The denver — Salt lake city radio relay route — Initial th 6,000-megacycle installations

The initial application of TH 6,000-mc (megacycle) microwave in the Bell System communications network on an existing long-haul TD-2 4,000-mc radio relay route between Denver and Salt Lake City proved the feasibility of such construction to augment the circuit capacity of existing TD-2 systems. The construction of building additions, conversion to 3-phase power, changing out of emergency engine alternators, antennas, and waveguide were vaccomplished without interruption to service on the TD-2 system. Subsequent construction will extend the TH facilities from coast to coast.
