SNOW ATTACHMENT PREVENTING DEVICE FOR ANTENNA

摘要

PURPOSE:To eliminate the snow attached onto the surface of antenna's reflector, by making use of the hot air of a forced air-cooled large-power amplifier. CONSTITUTION:The exhausted air of the forced air-cooled large-power amplifier 3 combined with the antenna 1 is introduced into the air-exhausting duct 5. The switching valve 7 of air-exhausting direction is provided in the duct 5 to send the exhausted air to the air exhausting duct 6 in fine weather and to the duct 5 when snow falls, respectively. The exhausted air in the duct 5 is then flowed out in the direction of the reflector of the antennal 1 through the air-exhausting hole 8.
