PURPOSE: To reduce the space of a radio communication equipment on the whole by positioning a sealed housing which contains a radio communication circuit part below a main reflection mirror and put a subordinate reflecting mirror which faces the horn antenna of the sealed housing as close to the antenna as possible.

CONSTITUTION: The sealed housing 30 which contains the reception part 31 of the radio communication circuit part and the principal part 32 of a transmission part consists of a box type main body part 33, a detachable lid 35 which covers and seals the aperture surface 34 of the main body part 33, and a high frequency amplification part 38 fitted detachably in contact with the external surface of the bottom part of the main body part 33. This device consists of a column 90 standing in the center of a leg part 89, a horizontal swiveling mechanism part 91 for a supporting table 98 above the prop, a transmission/reception part further above it, a tilt angle adjusting mechanism 94 which slants a frame body 92 for antenna support vertically around a horizontal shaft 93, a fixing screw 95 for fixation at a specific angle and a specific position, the subordinate reflection mirror 96 which is fitted nearby and opposite the opening of the antenna 75 of a transmission/reception part 30 fitted in the center of the lower part of the frame body 92 for every rack 80, and a large-diameter reflection mirror 97 which is fitted facing up.
