The website is good about showing which antennas support L1/L2, but are 100% silent on if they support the
L-band correction services?
Which Sparkfun antennas support the ZED-F9P, NEO-D9S combo board?
Does the Lightweight helical antenna support this?
If not can anyone recommend a lightweight antenna that supports the corrections?
For lightweight it seems digikey has a 37 gm helical…

L-Band specific reception antennas are fairly rare. We have one, specifically designed for L1/L2/L in the RTK Facet L-Band (https://www.sparkfun.com/products/20000) but that’s not really helpful to you because we don’t sell the bare element.
I’ve used the TOP106 (https://www.sparkfun.com/products/17751), and SPK6618H (https://www.sparkfun.com/products/21801) to receive L-Band use the NEO-D9S with very good success. Paul has used the u-blox mag mount (https://www.sparkfun.com/products/15192) with good reception as well.
But none of this answers the core of your question: light weight. I suspect (but have no idea) the helical antenna (https://www.sparkfun.com/products/17383) has reception bands and filters that may be wide enough to pickup L-Band. Testing required! I’ll see what I can rig up next week.
There’s a whole other question of L5 reception that should be figured out as well.
