I also have an old 204BA up temporarily and with no rope and it makes 
no noise.  I cannot see the rope playing any role in making "rattles" 
go away unless, perhaps the clamps are not tight...in which case your 
antenna will indeed be temporary ;-)

Sounds like you have some sort of loose mechanical "feature".
