Double reflector antenna for use with satellite - transmits and receives HF signals via satellite and directional earth propagation using main and sub-reflectors

摘要

The double reflector antenna has a U-shaped arm (3) extension. The main reflector (1) is at one end of the arm, and the sub-reflector (2) is at the other end of the arm. The arm fits in a holding mast (5) and is connected to a toothed support which allows height adjustment of the antenna. The antenna is adjusted in height by turning the toothed support through the M axis of the U-shaped arm extension. The axis lies on the parabolic axis (AH) of the main reflector and cuts it at a right angle. The main and sub-reflectors are positioned asymmetrically. The storage system (9) is tilted upwards and is located with the converter in a housing (10) at the back of the main reflector. ADVANTAGE - Can be dismantled for transportation purposes.
