WebRadio telescopes look toward the heavens to view planets, comets, giant clouds of gas and dust, stars, and galaxies. By studying the radio waves originating from these sources, astronomers can learn about their composition, structure, and motion. Radio astronomy has the advantage that sunlight, clouds, and rain do not affect observations. WebAttenuation of the cable = 0,69dB. ERP = 1000W x 10^ (8dB - 0,69dB)/10 = 3715W. Thus, the system described in the formula would effectively provide approximately 3 times the transmitter power, to an ERP of 3715 Watts, with a 152 kilometers coverage.
