Don’t be fooled by the small size of this high quality built antenna. We managed to achieve 2 km in semi urban area with BW = 125 kHz, CR = 4/5, SF = 7, CRC enabled and transmit power = 20 dBm on our Mini Ultra Pro board equipped with RFM95W using the Radiohead library. The range can be further extended by few more km by using higher spreading factor (SF) setting (for example SF = 12) on the RFM95W module. Available in 433 MHz, 868 MHz and 915 MHz bands. Each antenna is labelled by it’s frequency band (newer batch has it’s frequency embossed on the antenna itself!).
