This picture shows a flowerpot microphone and an older pyramid pressure zone microphone mounted on a roof in Alfred, New York USA. This station has operated every fall since 1991. The mikes are mounted on wood pallets that are tied down to the roof with strong rope. In the case of the flowerpot, you can see that it is propped up with sections of two by four wood blocks so that it is aimed vertically at the sky. The trees in the background are far enough away that their associated wind and insect noise is not a impediment. So, an important consideration before you build one of these microphones is to make sure that you have a suitable location to mount it; one without overhanging trees or close sources of insect or frog noise. Often the mike can be mounted on the roof so that the peak of the roof or some other structure can act as a barrier from direct wind buffeting. In the case above, the mikes are mounted on the south side of the roof's peak for fall migration monitoring. However, you want to make sure that structures on the roof are not so high above the mike that they reflect sound waves on an unimpeded vector to the microphone element. This will result in picking up reflected sound energy that will impede the clarity of the recorded sound.
