Hi John,

I believe that at least a partial answer to your question regarding
an antenna installation time specification is contained in the antenna
contract...

I believe that this is at least partially contained within the antenna
foundation and transportability specifications.  From the Vertex
antenna contract, section 3.5.3:

"Foundation connections to the antenna must provide azimuth axis
repeatability of +-2 millimeters for translation and +-25 arcseconds
for angular repeatability for multiple installations of the antenna on
the foundation."

...and from section 3.5.2:

"All connections and interfaces to the transporter and foundation must
be removable in less than 15 minutes and installable in less then 15
minutes.  This shall include all setting and calibrating of metrology
instruments, and removal and installation of platforms or ladders that
may be in the way for the attachment of the transporter."

Hope this helps.

Cheers,

Jeff
