433.92 mhz antenna
Hello,
Would it be possible to design a 433.92MHz preamplifier in order to increase the sensitivity of the receiver. The complete system serves as a wireless garage door opener and at the moment it is capable to achieve about 200 meters distance. It has a handheld transmitter, so it is not possible to modify it in order to achieve greater distance, because of the limited space and the battery consumption. The RF receiver board is made with SMD elements and it uses the integrated circuit UAA32017 from Philips. I do not know the signal to noise ratio of the receiver nor the input sensitivity. Is it possible to increase the distance to aprox. 400 meters and how would the electrical circuit look like. The receiver has an antenna connected to it and the antenna lenght is around 32 cm.
Regards.
