4.   GPS Antenna Information

4.1  Antenna Type             : DORNE MARGOLIN T
                              : TURBOROGUE L1/L2 GEOD (Mod. 7490400-4)
     Serial Number            : 438
     Antenna Height (m)       : 0.000
     Antenna Reference Point  : Bottom of the antenna
     Degree Offset from North :
     Antenna Radome Type      :
     Date Installed           : 23-MAR-1995
     Date Removed             : 07-SEP-1997
     Additional Information   : On March 1996 a metallic ring around the antenna was mounted
     in order to reduce the RFI. On 14 of May 1996 a different  metallic ring  was mounted.
     These two plates caused probabily a change on phase center on L1 and L2.
