Subject: No 0896 : Network/ Antenna change and raising at ST JOHN'S
#### END HEADER ####

Dear colleagues,

The  antenna of the DORIS station at ST JOHN'S (Canada) has been replaced
in order to overcome disruption on 400MHz and the antenna support has been
modified in the frame of a global action aiming at removing bent
connectors and standardizing the antenna support models.

The antenna is now supported by a 40 cm high stainless steel structure,
set on the same concrete pillar.

Please find below the installation characteristics and the coordinates of
the new reference point :
