Launch3 contacted me, this morning, and noted they received over 10 separate inquiries for the 59532A antenna within 3 hours after I posted on "time-nuts" (daily digest readers have not yet received notice).
For newbies, this is a great price (eBay sells the used antennas for $100 each),
and they are brand new.
The Internet has 99% of the questions posted, so far.  The answers are there, 
IF you know how to use your search engine (Google, Bing, etc.).

The Symmetricom 58532A GPS L1 Reference Antenna is an outdoor antenna.
The 58532a AUS option is a very simple kit of parts for mounting to a wall, or existing mast or tower leg. 
Your Answer is in the Specification Sheet I provided (and on Launch3 web site)
PAGE 2 : FIGURE 2 of the Specification Sheet tells you the SIZE of the Mast.
You see these Microsemi/Symmetricom mounting kits regularly sold on eBay (Launch3 may even have some), look at this eBay completed sale: 221735118342  ~ $20.00

IF you have ever installed a Diamond/Comet VHF/UHF base antenna -- 
this is the same mounting design type.
You can mount this to a wood structure, masonry wall, or existing pipe/mast (side of tower), as noted in Microsemi documents.

NOTE:  The antenna's "N" connector is on the bottom of the 58532A antenna.
These means that your coaxial feed must be routed inside your mounting pipe / mast -- 
IF you don't use the AUS kit of parts (or equivalent), then buy / acquire parts you need.

The Pictorials, in this document, may help you visualize.

Original message:
The Symmetricom data sheet mentions the Option AUB antenna mast. 
What is that? I don't find details of it. How does you mount the 58532A antenna 
if the Option AUB mast is not available?
