LNB Positioning System for Satellite Antenna (ANGLE CONTROLLING SYSTEM OF LOW NOISE BLOCKDOWN CONVERTER (LNB) FOR SATELLITE ANTENNA)

摘要

In order to optimize the elevation angle of the waveguide with respect to the focal distance of the reflector of the satellite antenna, the position adjusting device of the low noise blockdown converter (LNB) A pair of hinge shafts 46a and 46a formed on both sides of the waveguide 40 opposed to the reflection plate 12 while being coupled to the front of the housing 38 ' And an LNB main body 46 mounted on the one hinge shaft 46a so as to be rotatable up and down on the housing 38 'by pivoting means 46b for receiving upper / lower pivoting power, An electric elevation angle adjusting means 48 'installed on one side of the waveguide 40 to adjust the elevation angle of the waveguide 40 by transmitting electric rotary force to the rotation means 46b of the LNB main body 46, 40 and the front end of the housing 38 ' Gajigoseo always downstream from the elastic state is composed of an elastic member 50 for preventing the flow of the waveguide 40 containing LNB unit (46).
