Hi everyone,
We have recently (and finally) deployed a S-Band station that is built based on the following hardware:
- RPI 4 Model B with POE Hat
- Ettus Research B205mini
- RF AMP 04A LNA
- Sysmocom S-Band Cavity Filter: S-Band cavity filter 2170-2300 MHz | cf2235-kt30
- 2250MHz Helical Antenna made following this:
Helical antenna scaffold set (v4) by derekcz - Thingiverse
Initial observations seems to be promising. Please use the station and let us know any feedback on how we can improve it
