SUBSURFACE RADIO TRANSMISSION TESTS IN CHEYENNE MOUNTAIN.

Abstract

Propagation experiments were conducted in the Cheyenne Mountain area to determine the feasibility of hardened radio communication between NORAD COC (and nearby surface installations). An 800-foot antenna was placed in a drill hole parallel to and 700 feet below the surface of Cheyenne Mountain. Receiving and transmitting measurements were made with this buried antenna. Analyses of the experimental results indicate that the useful frequency range is from 70 Kc to 200 Kc. In this range, estimates have been made for single-channel or multichannel teletype transmission from the COC to distances of a few tens of miles. (Author)
