The issue is that the pilot keeps going out, I think due to wind pressures. It is fixed to a bungalow gable end in the loft area and within all acceptable Terminal positions in accordance with BS 5440. The next door bungalow, of a similar height is about 4 metres away. Is there anything that can be done to stop this from occurring?
