Like all disc ceramic capacitors with wire leads, they are not RF 
current-rated.  I have not tested them, but my guess is that they would 
carry up to 1A at 2 to 4 MHz.  
-  One source of high-current coupling capacitors is Jim Perkins [fax 209 
825 5599], who currently has a supply he removed from surplus Collins 
Radio Co. (4) 8170/4cx5000A amplifiers.  He also has the socket 
assemblies.
