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.

depends where you are situated, look for something like that http://tinyurl.com/7bmqw6q broadband amplifiers, they are cheap and you do the filtering by making a selective antenna.
Narrowband amplifiers are a little more expensive http://www.minikits.com.au/eme173.htm
