Now I wonder why the FAA specifies "woven lightning down leads" rather than 
solid conductors.  This lightning protection is located on the long range 
radars radome.  Several lightning rods (with very sharp points are locate 
around the external surface of the  radome.  These are connected to a 
ciruclar ring of woven cable which has a couple of woven down leads that 
eventuall connect to the tower down lead which is also woven wire (this is 
some pretty big wire and the "strands" are pretty healthy size.  For some 
reason solid coductors were prohibited.......
