  9. Amazon Special 5.8: 1.653 VSWR, S11 of -12.17

How a VNA tester translates into real-world improvement for LoRaWAN reception is unknown. Plus, measuring at 904 MHz used by Helium LongFi/LoRaWAN in the US (instead of exactly at 915) is probably more accurate...and the range that the PPL 5.0 antenna really excels at!
