All the choke ring antennas were similar in performance. The Aero/Leica one is optimized for the L1 freq only.
All the other choke rings that I tested did L1/L2 which compromises performance a bit which did show up in the data (but at a level that could just have been random luck of the draw). Where the L1 only antenna was getting precision survey offsets in the one inch area, the L1/L2 units were in the 2-3 inch area.
Lesser survey grade antennas might be in the 6-12 inch range. Conical timing antennas in the 1-2 foot range (they are just a higher quality patch antenna under a conical radome). Cheap automotive patch antennas in the 3+ foot range.
