   Need?....possibly not.   
      
   Desire?... probably yes.   
      
   Reasons:   
   1) The balun/unun will better match the antenna to the transmission line   
   and receiver. This will give you better receive performance which may,   
   or may not, matter to your application.   
   2) The balun/unun will provide a dc ground path for the antenna.  This   
   can prevent/reduce static buildup on the antenna. Your post is unclear   
   if you are really doing a beverage (which is terminated at both ends) or   
   a random wire antenna (which is not terminated at the far end). Static   
   buildup can harm the receiver.   
      
   Don't forget to use proper lightning protection.
