Dear Colleagues,

I have been notified from station BAKO that they installed a Leica AT504 GG 
antenna with LEIS radome on 1 January, and the antenna height changed to 1.648m.

There is no calibration for this equipment in igs05.atx, and although the IGS 
Site Guidelines (http://igscb.jpl.nasa.gov/network/guidelines/guidelines.html) 
state (2.1.8) "To use an antenna+radome pair not found in either of these files, 
contact the CB. A calibration from an independent, recognized laboratory such as 
NGS (http://www.ngs.noaa.gov/ANTCAL) or Geo++ (http://www.geopp.com) will be 
required," the CB was not notified in advance of this equipment change.

We understand that a calibration is forthcoming.  In the meantime, since site 
logs may not contain uncalibrated equipment, the revised site log cannot be 

Best regards,
