[Premium-Rx] FW: Free 13.7m parabolic dish

[George Georgevits]

Hello everyone.

Although this is not a premium receiver, it would have to qualify as a
premium antenna so I thought I would include it here for interest.

Subject: Free 13.7m parabolic dish


Dear John,
As secretary of the ASA i was wonder if you might distribute this to the
members.

CSIRO has been using two antennas at Marsfield that they obtained from the
University of Sydney Fleurs Observatory.  They were used for initial work on
ASKAP technologies. CSIRO now using higher performance antennas at Parkes.
CSIRO now wish to have one of the dishes removed from the Marsfield site.
Rather than just scrap the antenna CSIRO is offering it to any one who may
be able to reuse it on the basis that its removal will be at no cost to
CSIRO.

The antenna was completely refurbished in 2005 and is a 13.7m equatorial
mounted parabolic reflector set for the latitude of Sydney.
The surface is mesh and is good to beyond 1.8GHz.
The HA limits are +/-60 deg and Dec limits -75S to +10N.
The antenna will come complete with modern variable speed drives, encoders
and control system.  This should allow the dish to be operated at latitudes
different to Sydney's.

The mesh surface is attached with cable ties and much of the structure
unbolts to component ribs and trusses. After this
the largest components are the pedestal ~1.8m by 5m and the central hub
sections which are ~6m by 3m by 1m.
The major labour component in reassembling the dish is the reattachment of
the mesh

Any one interest is this antenna should contact John Bunton, email
