Reliable RF Amplifier for Robot Antenna Problem
Hi, it's me again. Does anyone know of a good reliable RF amplifier for the
433 MHz range? We need a gain of roughly 20 dB. We want to use it to amplify our received signal from the beacon. Thanks in advance for any help. PS We realized the thing about rotating the mesh was not an issue. Thanks for the replies to that Paul and Helmut. -Billy Maier |

Narrowband amplifiers are a little more expensive http://www.minikits.com.au/eme173.htm w. |

The goal being the one with the lowest noise factor and the most gain - while filtering out anything that would cause overload. Without a physical address - where I could see what else is in the neighborhood - there is no way for sure to answer your question. Anything from Police stations to ambulances to fire stations to GMRS and Amateur repeaters might create harmonics which could get into your amplifier and cause overload.
