Radio Transmission in Caves
Fielding McGehee


Radio communication between explorers working in caves and parties on the surface or in a different area of the cave will probably become standard procedure in years to come. Success in receiving a signal through rock depends on many factors - distance, the wetness of the rock, antenna loading - all are imporant. Here is the result of two experiments conducted by the author on the subject. He describes successes with the method, and points out areas in which there is much to learn. Radio, indeed, would be a useful tool for the speleologist to acquire, not only for communications, but for surveying and entrance finding.
