25.6 times worse than the Arduino antenna

The RSSI is similar to the Arduino antenna (a bit worse 2.3-times) but the SNR is 6-times better.
I will mount the ANT-8/9-SPNF2 antenna to a device to get some field measurements and see if this improves the Adlisberg-Trail situation.
Test some other antennas with more gain to see if this helps. (Additional advantage: pass through connector)
