Hi If you dig into the data on the antennas …. ( they are fully tested and doccumented …)
The Novatel design does a *very* good job. Indeed they are *much* better than an old style giant choke ring design. Normal list price is roughly 10X what that listing shoed. Similar antennas normally sell for $600 to $1200 on eBay. Indeed the 703 GGG *is* discontinued as a brand new product. That’s also true of a number of pretty expensive antennas you see on eBay. These are *not* the same thing as the low cost stuff from China.
