In Australia where aeolian vibration is severe, the BATE dampers suffered fatigue failure to themselves and the conductor at the attachment clamps. At vibration frequencies where the damper was inactive the clamps became a reflection point and bending stresses were imposed at those points. Efforts to improve the clamps have been made over the years but although this has alleviated the problem somewhat, the real problem is that the damping device does not respond to most of the frequencies experienced over the range of wind speeds causing vibration. With the addition of multiple festoons of varying lengths this limitation was somewhat alleviated.

In 1926 the stockbridge damper was invented (Figure 7) and when Monroe and Templin patented their improvements to it to respond to two frequency ranges it was introduced in Australia by Alconac Pty Ltd in 1950 and replaced the BATE damper almost completely (Figure 8).

The Monroe and Templin improvement on G H Stockbridge's design provided 2 degrees of freedom and usually responded to frequencies peaking at about 7Hz and 12Hz (Figure 9) for transmission size conductors up to 1 inch in diameter.
