FAQ

Can I use this Reach RS4 UHF Antenna on the 868/915 MHz LoRa frequency?

Absolutely not. This antenna is tuned exclusively to receive and transmit corrections via the built-in 410-470 MHz UHF radio. Trying to force it into a LoRa configuration will result in zero communication, endless frustration, and a deeply disappointing day on site.

Disclaimer

We are not legally responsible for missed deadlines because you ordered a UHF antenna when your base station is actually transmitting on LoRa. Double-check your radio frequencies before purchasing, or enjoy pacing around the site wondering why your equipment refuses to talk to each other.
