摘要： The invention relates to a method for aiming an antenna, in which method the antenna (A1, A2) is installed in a desired position in order to aim the antenna (A1, A2) at a target (A1, A2) for the reception, transmission or reception and transmission of radio signals. According to the invention, the direction (LOS) of the target (A1, A2) for selecting the position of the antenna (A1, A2) is determined using an optical sight (S, S1, S2, S3, S4, S5). Further according to the invention the sight (S, S1, S2, S3, S4, S5) is fitted in a predetermined position with respect to the position of the antenna (A1, A2) to be aimed, and the sight (S, S1, S2, S3, S4, S5) is aimed at the target (A1, A2) in order to determine at the same time the position of said antenna (A1, A2).

摘要： The invention relates to an adjustment joint for adjusting position, which adjustment joint (S1, S2) comprises at least two adjustment parts (S11, S12, S13, S21, S22, S23) adapted so as to be rotatable with respect to each other around (arrow R) a joint axis (A1, A2), and a locking element (S14, S15, S15a, S15b, S15c, S15d) functioning in the direction (arrow L) of said joint axis (A1, A2) for locking the adjustment parts (S11, S12, S13, S21, S22, S23) so that they become immobile with respect to each other. According to the invention, the adjustment joint (S1, S2) is adapted so as to be switched from the locked state to a fine adjustment mode by opening the locking element (S14, S15, S15a, S15b, S15c, S15d), which fine adjustment mode is arranged for preferably stepless fine adjustment of position. The adjustment joint (S1, S2) is adapted so as to be switched from the fine adjustment mode to a coarse adjustment mode by further opening the locking element (S14, S15, S15a, S15b, S15c, S15d), which coarse adjustment mode is arranged for preferably stepped coarse adjustment of position. The adjustment joint (S1, S2) is adapted so as to be switched from the coarse adjustment mode back to the fine adjustment mode and further from the fine adjustment mode to the locked state by tightening the locking element (S14, S15, S15a, S15b, S15c, S15d).
