✦ Synopsis

RATCL1FFE of the Cavendish Laboratory, Cambridge, England, reports that thunderstorms shatter the radio "mirrors" of electrical particles hundreds of miles above the earth and cause poor reception. These "mirrors" are layers of ionized gases. Radio waves bounce off the underneath side of these layers and are reflected back to earth.

The Cavendish investigator found one particular electrical layer to be 78 miles above the earth before a thunderstorm arrived. During the storm, the layer dropped to a height of 65 miles, then returned to the 78-mile level as the electrical disturbance abated. Fifteen minutes later it mounted to 93 miles.

Much the same type of investigation is being conducted by B.

This letter deals with the excitation of UHF radio wa¨es in tunnels. It is found that the antenna position and the antenna gain are two major factors that affect the excitation of radio wa¨es in tunnels. The antenna in the middle position and with high gain is preferable. Furthermore, the enhancemen
