433Mhz Communication & Interference tester

Hi everyone ,

I use a 433Mhz mobule communication system to report data from a mobile weather station to a base station.

There are situations where I need to know where the best place is to place the system in terms of communication strength.

Is there a module that allows me to test how good my system will communicate with the base station when placed at a certain position?
(In other words, tests interference and communication strength between 2 points)
