Although the receiver can provide Galileo and Beidou signals, the antenna does not support the L5 band, and therefore no Galileo or Beidou, or GPS L5, data is provided. 5302K41643 0.0 0.0 2018-12-17T14:38:00Z The receiver is capable of tracking L5 (lower part of L-band), but the antenna LNA is not optimized for L5 and therefore we do not recommend using the L5 band signals for serious work. 3024778 0.0 0.0 2020-02-18T19:23:00Z The receiver is capable of tracking L5 (lower part of L-band), but the antenna LNA is not optimized for L5 and therefore we do not recommend using the L5 band signals for serious work. 3024778 0.0 0.0 2023-04-17T15:37:00Z The receiver is capable of tracking L5 (lower part of L-band), but the antenna LNA is not optimized for L5 and therefore we do not recommend using the L5 band signals for serious work. 3024778 0.0 0.0 2023-04-17T15:37:00Z DUTD = polyester cone 273 0.3795 0.0 0.0 0.0 80.0 1997-06-01T12:00:00Z DUTD = polyester cone 273 0.3888 0.0 0.0 0.0 80.0 2023-12-07T20:41:00Z The antenna change involved replacing a metal adapter with a newly fabricated one. The new adapter did not introduce noticeable changes in the horizontal position: any differences, if they exist, should be below the millimeter. In the vertical, the ARP of the new antenna is 13.4 mm below the old ARP, as a consequence the antenna height is changed. 726840 0.3754 0.0 0.0 0.0 95.0 2023-12-07T20:36:00Z 5.0 1997-06-01 5.0 1998-02-28 5.0 1998-03-26 5.0 1999-05-18 2000-01-06 5.0 2019-02-13T18:24:00Z 10.0 2023-04-17T19:58:00Z 2023-12-07T20:41:00Z 10.0 2023-12-07T20:40:00Z 1997-01-01 1997-01-01 ARP: Antenna Reference Point L1 : L1 Phase Center L2 : L2 Phase Center TCR: Top of Chokering BCR: Bottom of Chokering ###########################################]]> ARP: Antenna Reference Point L1 : L1 Phase Center L2 : L2 Phase Center TCR: Top of Chokering BCR: Bottom of Chokering ###########################################]]>
