The L1 only antenna that did very well was an AeroAntenna AT575-75W-TNCF-000-RG-26-NM   Also a Racal LandStar MK4 did well.  These are both small L1 only survey antennas.

All my L1/L2 antennas are choke ring  survey/geodetic grade devices...  an equivalent  choke ring L1 only antenna should perform just as well on a Tbolt...  but I suspect very few people bother to make such a device.

Which of the L1-only antennas did well?
And do you have an explanation why the L1/L2 antennas did better,
even for the L1-only reception case?
