Get it Thursday, January 14 - Saturday, January 16. The best solution to either problem is to find a way to boost the incoming signal. What is the legal power limits for this frequency in your country? A Yagi array (TV antenna) will increase gain at the cost of omnidirection. The output signal of the RF generator is an analog sine (AM modulated or not modulated ) signal. Tighten any loose connections. You can see that with method the signal has been amplified before it has been allowed drop below the minimum strength or before it come weak. Is there a away to transmit sensor signal over RF without Arduino? Key points that you need to keep in mind: The scheme I used sent 64 bit data packets reliably if up to 100 meters. Is it because you do not get reliable communications within 10 meters? and as you are using an RF transmitter already, i can't see why it is not possible to amplify a signal you already have at … PCT 8 Port Bi-Directional Cable TV Splitter Signal Booster/Amplifier with Active Return Zero Signal Loss and VoIP Telephone Bypass,white.
