Dear colleagues,

In order to clarify the information regarding the USUD antenna height of
-.035m, the antenna diagram in the site log will be updated as follows:

         TURBOROGUE: DORNE MARGOLIN T

                         -----
                     /     +     \                        <--  0.128  L2
                    |      +      |                       <--  0.110  L1
  +--------------------------------------------------+    <--  0.102  TCR
  |                                                  |
  |                                                  |
  |                                                  |
  |                                                  |
+-+--------------------------------------------------+-+  <--  0.038
+-------------------+-------------+--------------------+  <--  0.035  BCR
                    |             |
                   =|             |
                    +------x------+                       <--  0.000  ARP

   ARP: Antenna Reference Point
   L1 : L1 Phase Center                   L2 : L2 Phase Center
   TCR: Top of Chokering                  BCR: Bottom of Chokering

I apologize for any confusion the previous antenna diagram may have caused.

Regards.
