Harris Stratex Networks (HSTX) and Ceragon Networks (CRNT), both companies which provide hardware used for wireless backhaul of cellular signals, are getting a nice bump this morning from a Friday afternoon endorsement by Jim Cramer on CNBC’s Mad Money. Cramer describes the two companies as “the two best pure plays on microwave backhaul radios,” used to connect cell towers to wireless networks.

Cramer speaks, Cramerica responds: HSTX this morning is up 54 cents, or 8.1%, to $7.22; CRNT is up 57 cents, or 7.8%, to $7.89.
