One very important difference I've found so far is the i.d. of the 
center conductor.  The older FHJ5-50A is 0.255 inch, while the newer 
LDF5-50A (and the Decibel/ATG stuff) is 0.295 inch.  Iearned this by 
pulling out my micrometer and measuring them. :)

WN3A pointed out another important difference -- the older cables have a 
spiral outer conductor, while the newer ones are annular rings.
