At least with a Tbolt, they do help... and quite a bit. When I was writing Lady Heather's precision survey code I tested it with several antennas (comparing the results to a cm level L1/L2 survey). The Leica antenna and a couple of other survey grade/choke ring antennas were, by far, the best (results with a foot or so). Cheap patch antennas were the worst (with maybe 5 foot errors).
Some small L1 only survey grade antennas did pretty well... a couple of feet. They are about 6 inches in diameter and and inch thick and very light. I use one as my standard antenna.
-----------------------------------
It’s not real clear that they have a significant advantage for L1 only operation with a Z3801.
