Hi John,
Since TOPCON is a manufacturer of topographic instruments, I think that
this antenna is used for this kind of work. GPS antennas made for
geodesy or surveying usually have a very good quality and their prices
are according to it.
But given the label at the bottom it could be used by UPS and its
subsidiaries installed on their trucks and vans for tracking them. In
this case the antenna class is a common navigation one.

Hey all,
I'm looking for a specs sheet for an antenna i recently got my hands on. It's
marked Topcon on the top, II Morrow Inc model 590-1114 on the bottom. I've
tried searching in all the usual places but haven't found anything yet. If
anyone could send anything my way that would be much appreciated!
