In the UK, the recommended height is 10 metres. Advice varies on whether you should correct for a lower height.
== Where should I position the rain sensor ==
See [[Rain measurement]]
Officially the rain gauge should at a distance away of 2 to 4 times the height of each nearby object, (varies between different guidance). You can experiment, but for amateurs, no more than a metre off the ground (or roof if mounted above it) (not possible for Davis stations if temperature measuring criteria met) and at least a metre from any wall or solid fence whose height exceeds that of the sensor seems good.
 
You will find lots of discussions about wind effects, and rain shadows online, together with research for siting requirments in rural and urban locations.
