I might have misunderstood the device.  Says:

The band-pass filters used are wide enough to let this splitter work with all frequency channels assigned for commercial use (GPS at 1575.42 MHZ, Beidou at 1561.098 MHZ, GLONASS at 1602 MHZ center frequency and Galileo at 1575.42 +/- 12.3 MHZ.

I’ll need to do more research

Sorry and thanks for bandwidth

You really want an L1 only splitter?

Yes, those are the L1 bands, but newer GNSS receivers also use L2, L5,
E6, etc.

Here is a good list of frequencies:

https://www.rfwireless-world.com/Terminology/GPS-Frequency-Band-and-GNSS-Frequency-Band.html

You can buy good receivers for L1/L2, or L1/L5, for well under what
that splitter/amplifier will cost you.  You will own one soon.

Hi,

A nice diagram of the bands is available at:
