PURPOSE: To provide a base plate for antenna by which the direction of an antenna is easily adjusted with high precision, in order to transmit/receive a signal in a best state. CONSTITUTION: The direction of this base plate is easily adjusted with high precision, by using a swing shaft support means that turns a base plate element 1, a 1st adjustment means that is placed to deliver the direction of turning of the base plate around a 1st orthogonal shaft and a degree of the turning. First and 2nd adjustable support means that are placed apart from the swing shaft support means at an angle and arranged for same directional or reverse directional adjustment turn the base plate element 1 around a 2nd orthogonal shaft or a 3rd orthogonal shaft facilitate the adjustments. |
