In addition, the curvature of the earth also comes into play. For a 2.4 GHz transmission path to transmit 5 miles, you would need antennas at 9.6 m (31 ft). For 900 MHz at 20 miles (32 km), you would need antennas of at least 46 m (152 ...Since the NRF24L01+ uses power in the 15 mA range and the Uno listed a 3.3 V supply capability of 50 mA, a separate supply seems unnecessary. However, a capacitor can help even out power spikes or deficits from the Arduino. Caption: Amplifier and antenna result in a longer range, but also a much larger size.Set the RF signal source for a strong signal modulated with a 1 kHz tone set for 3 kHz deviation (60% of the receiver's normal bandwidth). For 2.5 kHz wide systems, you would set the deviation to 1.5 kHz. Adjust the distortion meter for its reference level of either 0 dB or 100%, then adjust the tuning for minimum distortion level.Receiver Sensitivity and Noise.

Features of RF Module: 1.Receiverfrequency 433MHz. The 5881ENH wireless receiver sensitivity and noise rejection feature are both dynamically adjusted to match the ambient conditions of your property. If unacceptably high noise levels or low RF signal levels are detected, a trouble signal will be generated by your security system. Anytime the Honeywell 5881ENH sees an RF signal at the 345MHz ... As the bandwidth B increases, the sensitivity number increases and therefore the receiver becomes less sensitive. (E.g. when the receiver sensitivity goes from -90 dBm to -60 dBm, it has become less sensitive). A ten fold increase in bandwidth - for example from 10 kHz to 100 kHz - reduces the sensitivity by 10 dB.The specifications are categorized into RF upconverter and RF downconverter parts.
