I completed a 48 hour survey on a Thunderbolt with that Leica L1 choke ring antenna.  Might just be luck of the draw,  but lat and lon were under 1 inch error.   Alt was off by 1.25 feet.   I'm impressed...

The Leica AT303 L1/L2 choke ring antenna was around 5 inches error lat/lon,  1 foot alt.


Get back to school stuff for them and cashback for you.
