In addition, the dielectric material may comprise pieces of tubing or other tubular, hollow members formed from various dielectric, non-conductive materials, such as plastic, rubber, composite materials, other dielectric materials, etc."  I take that to mean that the spacers don't do anything except .... space the ends of the elements and close the bowties visually and mechanically.[/QUOTE]
