Probably the only thing you can realistically do is make a pair of directional antennas (one for the transmitter and one for the receiver) and point them right at each other, hoping that they don't line up with the interfering stations. The power of RC transmitters is absolutely limited by the FCC, but especially note that for greater power, you can not use the 72mhz band which are the normal RC frequencies, but rather, the designated Ham RC frequencies of 27mhz and 50mhz. That is 31 dB so the amplifier would need to be multi stage. ... An amp will of course increase the range of the transmitting device but at those frequencies they are not very forgiving and … 2) Antenna height. The antenna that you use for both the transmitter and receiver can really affect the range you’ll be able to obtain with these RF modules. To increase the range a wire can be soldered with the antenna. This type of RF module has distance range up to 200 meters according to datasheet but when i bought this RF module from Aliexpress its distance rang was very low, but i set its adjustable RF coil very carefully and i get very higher distance rang. But i’m ordered 2 kits of Geeetech-433Mhz-Superheterodyne-3400RF (delivery in 4-6weeks) and one aurel rx-4m50rr30sf (delivery morning). For short range, low-budget communication between two microcontrollers, one of the most preferred medium used is Radio Frequency (RF) communication using the 433MHz RF transmitter and receiver modules. Hi there, i have just a little quetion regarding 433mHz modules, like the TX118SA Transmitter and RX480 Receiver. Connect the TX(Transmission) pin of UART with ATAD pin of RF transmitter. Hi, I am trying to design a RF transmitter using the saw resonator for 433 Mhz. Arduino with RF 433MHz Transmitter/Receiver Modules. Circuit and working. 433MHz RF Transmitter is one of the best and most efficient RF modules. How to increase the range of FM transmitter circuit Below are the ways for long-range FM transmitter : 1) Increase one more stage, the amplifier stage. I’m already using this crap receiver (17.5cm 0.6mm wire as antenna) with bad range (max 1-4meter). Hi Im trying to increase the distance of transmission for my wireless circuit, Im currently using an RF module (433mhz) and im getting around 30meters im trying to get at least 50 to 100 meters. It is one of the cheapest receivers and has low power consumption. (Don't play with RF coil if your module works good), You also have to use a 6 inch antenna to increase distance range to max as possible. What I really need to do is to increase the range. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna. So i also recommend you to use low baud rate when working with tiny short range 433 MHz RF receiver and transmitter. In fact without an antenna you’d be lucky to communicate over a distance of more than a meter. Ground GND pin of RF transmitter. Any obstructions in the line of sight also affect the range. Several ways are available. 433 MHz Coil Loaded Antenna: In my 433 MHz projects I have been using a cheap (0.70 cnts) pair of Tx/Rx modules. Higher power transmitter: Higher power transmitters can effectively translate into more decibels at the receiver.
