Query: bad sensitivity at low temperatures

When outsite temperature is around 0 Celsius degrees or below, and the car and the unit it's not yet warm enough the detector acts very strange, it gives sudden false alarm like K 1 2 3 4 5 5 5 5 5 5 55 5 0 0 0 , Ku alarm 1 2 3 4 5 5 5 5 5 5 5 in spots where when it has normal temperature gives no alarm. And sometimes when on the highway , from nothing it gives a sudden alarm of strength 5 5 55 5 and then nothing my old cobra had no strange alarms like this one and it was smaller .the spiral coil it's not good to short , you need a straight onemaybe the scale would be better if it was from 0 to 9
