[OKDXA] Splicing wire in a dipole question

[John Geiger (AF5CC)]

My dipole had an unfortuate encounter with a neighbor's tree branch on Wednesday evening during a storm, and is now going to require some repair or replacing.  One option is to fix it by splicing a few pieces of copper wire together.  This is the cheap option.  However, could this cause problems later on?  I am wondering if the junctions of the wire could corrode and start acting like a diode, throwing out RFI all over the place?  

Could this happen, or is splicing copper wire in a dipole usually ok?
