CONCENTRATION OF RISK [Abstract]
CONCENTRATION OF RISK	NOTE 9 - CONCENTRATION OF RISK Because the Company sells into markets dominated by a few large service providers, a significant percentage of consolidated revenues and consolidated accounts receivable relate to a small number of customers. One customer of the Company's Satellite business unit accounted for 24% and 27% of consolidated revenues for the three months ended May 31, 2013 and 2012, respectively, and 21% and 18% of consolidated net accounts receivable at May 31, 2013 and February 28, 2013, respectively. One customer of the Company's Wireless DataCom segment accounted for 10% of consolidated revenues for the three months ended May 31, 2012. A substantial portion of the Company's inventory is purchased from one supplier, which functions as an independent foreign procurement agent and contract manufacturer. This supplier accounted for 63% and 57% of Company's total inventory purchases in the three months ended May 31, 2013 and 2012, respectively. As of May 31, 2013, this supplier accounted for 62% of the Company's total accounts payable. Some of the Company's components, assemblies and electronic manufacturing services are purchased from sole source suppliers.
