Steve,

This is a well-known effect.  The capacitance of the streamers
acts as a larger coil top load, and reduces the resonant frequency.
The coil may also benefit from the delayed breakout when the
tuning frequency is lower.  This tends to reduce the number of
streamers, but makes them longer also.
