How do you increase RF signal strength?
Use higher gain antennas and low loss feeder. Pump up the power of transmitter. Work at lower frequencies such as VHF. Use more sensitive receiver.
Is 433 MHz legal in USA?
The US Federal Communications Commission (FCC) regulates operation at 433 MHz under Regulation 10CFR47 Part 15.231. This frequency band is intended for remote control, and although other uses are allowed such uses are not optimal.
What is the typical operational range of 434 MHz RF modules?
Learn about the RF transmission and basic setup of the RF transmitter and receiver modules. The typical operational range of 434 MHz RF modules is between 50 metre to 80 metre. The operational range of the RF module can be increased manifold by attaching external antennas to the RF transmitter and receiver.
What is the power supply of RF transmitter and receiver?
The antennas of height 17.25 cm are connected to pin 4 of the RF transmitter in transmitter section and pin 8 of RF receiver in the receiver section. The power supply to the circuits is provided by 9V batteries. In first and second phase of the experiment, single 9V batteries are used to power the circuits.
What size inductor do I need for a 10th wavelength antenna?
For a tenth wavelength strip on a board with hand effects included, the antenna has a capacitive reactance of about 150 ohms. At 433.9 MHz, this would require a 56 nH inductor to cancel the capacitive reactance of the 2.7 inch (70 mm) long line. The document also describes spiral, chip and loop antennas (a.o.).
How many ohms is the impedance of an antenna?
If the trace runs parallel to ground, the real part of the antenna impedance will be approximately 10 ohms. In a hand-held unit, the impedance will be raised substantially through hand effects. For a tenth wavelength strip on a board with hand effects included, the antenna has a capacitive reactance of about 150 ohms.
