Bird Spike Kit (optional)
The optional Bird Spike Kit for WXT transmitters and WMT sensors is
designed to reduce the interference that birds cause to the wind and rain
measurement. The kit consists of a metallic band with spikes pointing
upward. The kit is installed on top of the sensor, and attached with a
screw. The shape and location of the spikes has been designed so that
the interference with wind and rain measurement is minimal.
The spikes are designed not to hurt the birds; they are simply a barrier
to make it more difficult for birds to land on top of the sensor. Note that
the bird spike kit does not provide complete protection against birds, but
it does render the sensor unsuitable for roosting and nest building.
Note that when the kit is in place, more snow can accumulate on the
sensor, and the snow may melt slower.
