antenna itselfout on 2005-05-17 due to apparent antenna problem.                             Serial number is now as hown in 4.2.  Mounting location is same and original                                   LEIAX1202 antenna was unscrewed from the mount and the replacement LEIAX1202 was                               screwed onto the same mount.  There is probably a few millimeters difference in                                position because of screw threads after 2005-05-17 at 14:45(Z)
