ATMOSPHERIC RADIO NOISE DATA, BANKOK, THAILAND - SEPTEMBER-NOVEMBER 1966

Abstract

Measurements were made of atmospheric radio noise at a joint Thailand-United States-organization in Bangkok. The noise-measuring equipment, modeled after the U. S. National Bureau of Standards Radio Noise Recorder, Model ARN-2, is located near the village of Laem Chabang, about 90 kilometers southeast of Bangkok, in order to minimize interference from man-made noise. A view of the site, showing the standard ARN-2 antenna and ground plane, is presented. For convenience in applying the results in this study, a nomogram for transforming effective antenna noise figure to noise field strength as a function of frequency is presented.
