Unaudited interim condensed consolidated financial statements	'
	Note 1 - Unaudited interim condensed consolidated financial statements
	The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments, which are normal and recurring, have been included in order to make the information not misleading. Information included in the consolidated balance sheet as of October 31, 2013 has been derived from, and certain terms used herein are defined in, the audited financial statements of the Company as of October 31, 2013 included in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the year ended October 31, 2013 that was previously filed with the Securities and Exchange Commission (“SEC”). Operating results for the three and six month periods ended April 30, 2014 are not necessarily indicative of the results that may be expected for the year ending October 31, 2014. The unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended October 31, 2013.
	Principles of consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts of RF Industries, Ltd. and its wholly owned subsidiary, Cables Unlimited, Inc. (“Cables Unlimited”), collectively (the “Company”). All intercompany balances and transactions have been eliminated in consolidation.
	Revenue recognition
	Four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. The Company recognizes revenue from product sales after purchase orders are received which contain a fixed price and the products are shipped. Most of the Company’s products are sold to continuing customers with established credit histories.
	Reclassifications
	Certain amounts in the prior period condensed consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported consolidated net income.

Discontinued operations	'
	Note 2 - Discontinued operations
	During 2013, the Company sold its RF Neulink and RadioMobile divisions, which together had comprised the Company’s RF Wireless segment. The divisions were sold pursuant to asset purchase agreements, whereby no purchase price was paid at the closing. Rather, the agreements stipulated royalty payments from each of the purchasers over a three year period. For the three and six months ended April 30, 2014, the Company recognized approximately $9,000 and $14,000, respectively, of royalty income related to the RF Neulink Agreement, which amounts have been included within discontinued operations. For the three and six months ended April 30, 2014, the Company recognized approximately $30,000 and $33,000, respectively, of royalty income related to the RadioMobile Agreement, which amounts have been included within discontinued operations.
	The following summarized financial information related to the RF Neulink and RadioMobile divisions is segregated from continuing operations and reported as discontinued operations for the three and six months ended April 30, 2014 and 2013 (in thousands):

Earnings Per Share [Abstract]	'
Earnings per share	'
	Note 4 - Earnings per share
	Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding increased by the effects of assuming that other potentially dilutive securities (such as stock options) outstanding during the period had been exercised and the treasury stock method had been applied. Potentially dilutive securities totaling 228,903 and 23,279 for the three months ended April 30, 2014 and 2013, and 228,069 and 161,559 for the six months ended April 30, 2014 and 2013, respectively, were excluded from the calculation of diluted per share amounts because of their anti-dilutive effect.
	The following table summarizes the computation of basic and diluted weighted average shares outstanding:
		Three Months Ended April 30,		Six Months Ended April 30,
		2014	2013	2014	2013
	Weighted average shares outstanding for basic earnings per share	8,208,278	7,610,309	8,175,376	7,337,101

Stock-based compensation and equity transactions	'
	Note 5 - Stock-based compensation and equity transactions
	The Company’s current stock incentive plan provides for the granting of qualified and nonqualified options to the Company’s officers, directors and employees. Incentive stock options granted to the Company’s employees during the six months ended April 30, 2014 generally vest and are exercisable equally over three years and expire in five years from date of grant. During the six months ended April 30, 2014, the Company granted a total of 205,323 incentive stock options to Company employees. The Company satisfies the exercise of options by issuing previously unissued common shares.
	The weighted average fair value of employee and non-employee directors stock options granted by the Company during the six months ended April 30, 2014 and 2013 was estimated to be $1.99 and $1.12 per share, respectively, using the Black-Scholes option pricing model with the following assumptions:
		2014		2013
	Risk-free interest rate	1.11	%	0.36	%
	Dividend yield	4.38	%	4.17	%
	Expected life of the option	5.0 years		3.5 years
	Volatility factor	52.9	%	42.9	%
	Expected volatilities are based on historical volatility of the Company’s stock price and other factors. The Company used the historical method to calculate the expected life of the 2014 option grants. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options’ expected life. The dividend yield is based upon the historical dividend yield.
	Issuances of common stock by the Company
	During the six months ended April 30, 2014, the Company issued 167,768 shares of common stock and received net proceeds of $462,000 in connection with the exercise of employee stock options.
	Company stock option plans
	Descriptions of the Company’s stock option plans are included in Note 8 of the Company’s Annual Report on Form 10-K for the year ended October 31, 2013. A summary of the status of the options granted under the Company’s stock option plans as of April 30, 2014 and the changes in options outstanding during the six months then ended is presented in the table that follows:
				Weighted
				Average
		Shares		Exercise Price
	Outstanding at November 1, 2013	988,215		$	2.24
	Options granted	228,903		$	6.39
	Options exercised	-167,768		$	2.76
	Options canceled or expired	-67,503		$	2.1
	Options outstanding at April 30, 2014	981,847		$	3.13
	Options exercisable at April 30, 2014	651,868		$	1.88
	Options vested and expected to vest at April 30, 2014	974,699		$	3.1
	Weighted average remaining contractual life of options outstanding as of April 30, 2014: 5.04 years
	Weighted average remaining contractual life of options exercisable as of April 30, 2014: 4.75 years
	Weighted average remaining contractual life of options vested and expected to vest as of April 30, 2014: 5.05 years
	Aggregate intrinsic value of options outstanding at April 30, 2014: $3.0 million
	Aggregate intrinsic value of options exercisable at April 30, 2014: $2.8 million
	Aggregate intrinsic value of options vested and expected to vest at April 30, 2014: $3.0 million
	As of April 30, 2014, $495,000 of expense with respect to nonvested share-based arrangements has yet to be recognized which is expected to be recognized over a weighted average period of 4.55 years.
	Non-employee directors receive $30,000 annually, which amount is paid one-half in cash and one-half through the grant of non-qualified stock options to purchase shares of the Company’s common stock. During the six months ended April 30, 2014, the Company granted each of its three non-employee directors 7,860 options. The number of stock options granted to each director was determined by dividing $15,000 by the fair value of a stock option grant using the Black Scholes model ($1.91 per share). These options vest ratably over fiscal year 2014.
	Stock option expense
	During the six months ended April 30, 2014 and 2013, stock-based compensation expense totaled $271,000 and $107,000, respectively. During the three months ended April 30, 2014 and 2013, stock-based compensation expense totaled $224,000 and $74,000, respectively. For the six months ended April 30, 2014 and 2013, stock-based compensation classified in cost of sales amounted to $30,000 and $25,000, respectively, and stock-based compensation classified in selling and general expense amounted to $241,000 and $82,000, respectively.

Risks and Uncertainties [Abstract]	'
Concentrations of credit risk	'
	Note 6 - Concentrations of credit risk
	Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents with high-credit quality financial institutions. At April 30, 2014, the Company had cash and cash equivalent balances in excess of Federally insured limits in the amount of approximately $12.3 million.
	One customer accounted for approximately 33% and 52% of the Company’s net sales for the six month periods ended April 30, 2014 and 2013, respectively. This same customer accounted for approximately 30% and 50% of the Company’s net sales for the three months ended April 30, 2014 and 2013, respectively. At April 30, 2014 and October 31, 2013, this customer’s account receivable balance accounted for approximately 24% and 27%, respectively, of the Company’s total net accounts receivable balances.  Although this customer has been an on-going major customer of the Company continuously during the past 15 years, the written agreements with this customer do not have any minimum purchase obligations and the customer could stop buying the Company’s products at any time and for any reason. A reduction, delay or cancellation of orders from this customer or the loss of this customer could significantly reduce the Company’s future revenues and profits.
	Sales of one product line accounted for $399,000 or 7% of net sales and $1.5 million or 13% of net sales for the three and six months ended April 30, 2014, respectively. The Company has a standard written purchase order with this customer and, therefore, this customer does not have any minimum purchase obligations and could stop buying the product at any time. A reduction, delay or cancellation of orders for this product or the loss of this customer could significantly reduce the Company’s revenues and profits.

Segment Reporting [Abstract]	'
Segment information	'
	Note 7 - Segment information
	The Company aggregates operating divisions into operating segments which have similar economic characteristics and divisions are similar in the majority of the following areas: (1) the nature of the product and services; (2) the nature of the production process; (3) the type or class of customer for their products and services; (4) the methods used to distribute their products or services; (5) if applicable, the nature of the regulatory environment. The Company currently has three segments - RF Connector and Cable Assembly, Cables Unlimited and Medical Cabling and Interconnector based upon this evaluation. During fiscal 2013, the Company disposed of its RF Wireless segment.
	The RF Connector and Cable Assembly segment is comprised of two divisions, whereas the Cables Unlimited segment and the Medical Cabling and Interconnector segment are each comprised of one division. The three divisions that meet the quantitative thresholds for segment reporting are Connector and Cable Assembly, Cables Unlimited and Bioconnect. The other division aggregated into the RF Connector and Cable Assembly segment has similar products that are marketed to their respective customer base and production and product development processes that are similar in nature. The specific customers are different for each division; however, there is some overlapping of product sales to them. The methods used to distribute products are similar within each division aggregated.
	Management identifies the Company’s segments based on strategic business units that are, in turn, based along market lines. These strategic business units offer products and services to different markets in accordance with their customer base and product usage. For segment reporting purposes, the Company aggregates the Connector and Cable Assembly and Aviel divisions into the RF Connector and Cable Assembly segment, while the Cables Unlimited division constitutes the Cables Unlimited segment. The Bioconnect Division comprises the Medical Cabling and Interconnector segment.
	As reviewed by the Company’s chief operating decision maker, the Company evaluates the performance of each segment based on income or loss before income taxes. The Company charges depreciation and amortization directly to each division within the segment. Effective beginning with the second quarter of fiscal 2013, the Company changed its measurement of segment profit or loss whereby certain corporate costs, previously attributed to the RF Connector and Cable Assembly segment, have been allocated to each of the segments. Certain amounts in the fiscal 2013 segment tables have been reclassified to conform to the fiscal 2014 presentation to reflect all segment information on a comparable basis. Additionally, with the sale and discontinuation of the RF Neulink and RadioMobile divisions during fiscal 2013, the segment information has been adjusted as these divisions are reflected within discontinued operations. Accounts receivable, inventory, property and equipment, goodwill and intangible assets are the only assets identified by segment. Except as discussed above, the accounting policies for segment reporting are the same as for the Company as a whole.
	Substantially all of the Company’s operations are conducted in the United States; however, the Company derives a portion of its revenue from export sales. The Company attributes sales to geographic areas based on the location of the customers. The following table presents the sales of the Company by geographic area for the three and six months ended April 30, 2014 and 2013 (in thousands):

Income tax provision	'
	Note 8 -Income tax provision
	The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter.
	The provision for income taxes was 40.3% and 28.8% of income from continuing operations before income taxes for the three months ended April 30, 2014 and 2013, respectively, and 35.2% and 28.3% of income from continuing operations before income taxes for the six months ended April 30, 2014 and 2013, respectively. The change in the effective income tax rate from period to period was primarily driven by changes in the rate resulting from the reversal of cumulative compensation expense related to disqualifying disposition of incentive stock options under ASC 718.
	The total amount of unrecognized tax benefits was $0 as of April 30, 2014 and October 31, 2013. The gross liability for income taxes related to unrecognized tax benefits, if any, is included in other long-term liabilities in the Company's condensed consolidated balance sheets.
	The total balance of accrued interest and penalties related to uncertain tax positions was $0 as of April 30, 2014 and October 31, 2013. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense and the accrued interest and penalties are included in deferred and other long-term liabilities in the Company's condensed consolidated balance sheets. There were no material interest or penalties included in income tax expense for each of the three and six months ended April 30, 2014 and 2013.
