Officially the rain gauge should at a distance away of 2 times the height of each nearby object (buildings, trees, walls, solid fences etc.) and just high enough off ground level to avoid possibility of splashing.  
The WMO says the rain gauge should at a distance away of 2 times the height of each nearby object (buildings, trees, walls, solid fences etc.) and just high enough off ground level to avoid possibility of splashing. You can experiment, but for amateurs, no more than a metre off the ground (or roof if mounted above it) and at least a metre from any chimney, wall or solid fence whose height exceeds that of the sensor seems good enough for most gauges.

You can find lots of discussions online about wind effects, and rain shadows, together with research on positioning requirements in rural and urban locations. A good starting point is [http://www.rmets.org/weather-and-climate/observing/guidelines-observing-0 this UK website].
