A satellite communication antenna including a preset balancer according to an embodiment of the present invention comprises: a reflection plate; a reflection plate flange which is provided in a rear central portion of the reflection plate to rotate with the reflection plate; a cross level arm which is connected to the reflection plate flange to be rotated such that an elevation angle of the reflection plate is variable; a main post which has an upper end connected to a central portion of the cross level arm such that the cross level arm is rotated; and a Ku-band processing module or a Ka-band processing module which is provided to be mounted on the reflection plate flange or separated from the reflection plate flange and receives or transmits radio waves of different frequency bands. In the process of mounting the Ku-band processing module or the Ka-band processing module on the reflection plate flange, a preset balancer for maintaining a load balance can be formed in the Ku-band processing module or the Ka-band processing module. By providing the preset balancer, it is unnecessary to perform a subsequent work for balancing a load applied to the satellite communication antenna after the Ku-band processing module or the Ka-band processing module is replaced. |
