An antenna alignment method for example for application to transmit/receive band satellite ground terminals, and a peak search tool for the realization of this method. In the method, from the antenna, a test signal is transmitted over an uplink channel to the satellite. Over a downlink channel from the satellite is received a sequence of alignment accuracy indications for the test signal. On the basis of the sequence of alignment accuracy indications, adjustments to the antenna's orientation for the alignment parameter are made. The peak search tool has an input adapted to receive a sequence of alignment accuracy indications each somehow indicative of alignment accuracy, a maximum alignment accuracy indication finder functional entity adapted to identify when a best alignment accuracy indication has been received in the sequence of alignment accuracy indications, a direction finder functional entity adapted to make a determination from the sequence of alignment accuracy indications whether a most recent adjustment step made by the installer has resulted in an improvement or degradation, and an indicator adapted to indicate to the installer the determination made by the direction finder functional entity.
