You stated 180 down to 166.  This will vary day to day and will depend where in your coverage area the aircraft are placed so nothing to worry about.  If it was down to 30-50 miles then its time to worry and I  will bet it will go up again.  I see from your polar diagram you have some areas further out than others so it all depend on where the aircraft fly in relation to your antenna.
