There are many types of cable designated RG-6 and RG-59.  Many are not 
designed to handle rf voltages typical of ham transmissions.  My 
suggestion is to be *careful* what you select.  Good quality RG-59, the 
type broadly used by hams many years ago, is hard to find right now.  
We're not talking about what the cable companies are using - we're 
talking about what you can buy at Wal-Mart or Home Depot.
