SFX2-458-5 : 500mW NBFM Multi-channel UHF Transceiver, 458MHz (UK), 500mW

SFX2-458-5 Transceiver

• UHF Narrowband FM High Power Radio Transceiver
• Frequency: 420MHz to 480MHz on any 4MHz band
• Data Rate: 5kbps
• RX Sensitivity : -118dBm
• TX Power: 100mW to 500mW

Overview

The SFX2 transceiver module offers a 500mW RF power output in the UK 458MHz band. This makes the SFX2 ideally suited to those low power applications where existing multi-channel narrow band devices like TR2M have insufficient range.
