There are two other sites that could tell a good antenna from the rest.
http://www.ngs.noaa.gov/ANTCAL/
http://gnpcvdb.geopp.de/pcvdb/GNPCVDB.html (The actual data costs )
There are antennas not listed on the above sites that perform quite well.
But all serious surveying grade antennas would be mentioned on the above
sites.
