Subsequent Events [Abstract]
Subsequent Events [Text Block]	Note 6 – Subsequent Event Subsequent to December 31, 2013, the Company received an unsolicited offer to buy Adams Global Communications LLC (“AGC”). The Company elected to pursue this opportunity to sell AGC as management determined that AGC did not fit within the Company’s primary cable television equipment distribution business of selling new and used headend and access and transport equipment, and AGC was not performing to the Company’s expectations. On January 31, 2014, the Company entered into an agreement to sell the majority of the net assets and operations of Adams Global Communications to Adams Cable Equipment, a supplier of customer premise equipment (“CPE”) and other products for the cable television industry, for approximately $2 million in cash. As part of the sales agreement, ADDvantage retains their existing relationship with ARRIS, as well as non-CPE inventory consisting primarily of headend and access and transport equipment. In addition, ADDvantage will retain the AGC facility. As part of the agreement, the Company also agreed to not compete in the used CPE market for three years. AGC’s net assets that were disposed of consisted of approximately $2.6 million of current assets, $0.5 million of noncurrent assets and $0.1 million of current liabilities, which will yield a loss on the sale, net of tax, of approximately $0.6 million.
