I would like to know what types of GNSS antennas are on the images below (patch etc.) and also which one is better from the two (if any). They are being sold as "high precision" survey grade antennas.

Photos of antenna internals were send to me by the sellers. Antenna #2 looks like a stacked patch type but I can not recognize type for antenna #1.

Antenna #1 (Buestues/High Gain HG-GOYH7151) gnss antenna enter image description here enter image description here

Datasheet #1

Antenna #2 (TOPGNSS/STOTON GN-GGB0710) enter image description here enter image description here

Datasheet #2 (dimensions include antenna housing)

  • \$\begingroup\$ From the specifications there seems little to differentiate. The second has a wider LNA voltage range which may not matter but is lighter which may. Both look pretty nice and would have cost 20 times more 20 years ago. \$\endgroup\$ – KalleMP Apr 26 '18 at 16:40
