I,
      James
      Doss, certify that:




1.  I
      have
      reviewed this quarterly report on Form 10-QSB of RF Industries, Ltd. (“small
      business issuer”);




2.  Based
      on
      my knowledge, this quarterly report does not contain any untrue statement of
      a
      material fact or omit to state a material fact necessary to make the statements
      made, in light of the circumstances under which such statements were made,
      not
      misleading with respect to the period covered by this quarterly report;




3.  Based
      on
      my knowledge, the financial statements, and other financial information included
      in this quarterly report, fairly present in all material respects the financial
      condition, results of operations and cash flows of the small business issuer as of, and
      for, the periods presented in this quarterly report;




4.  The
      small business issuer’s other certifying officer and I are responsible for establishing and
      maintaining disclosure controls and procedures (as defined in Exchange Act
      Rules
      13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
      defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer and
      we
      have:




a)  Designed
      such disclosure controls and procedures, or caused such disclosure controls
      and
      procedures to be designed under our supervision, to ensure that material
      information relating to the small business issuer, including its consolidated subsidiaries,
      is made known to us by others within those entities, particularly during the
      period in which this quarterly report is being prepared;




b)  Designed
      such internal control over financial reporting, or caused such internal control
      over financial reporting to be designed under my supervision, to provide
      reasonable assurance regarding the reliability of financial reporting and the
      preparation of financial statements for external purposes in accordance with
      generally accepted accounting principles;




c)  Evaluated
      the effectiveness of the small business issuer’s disclosure controls and procedures and
      presented in this report our conclusions about the effectiveness of the
      disclosure controls and procedures, as of the end of the period covered by
      this
      report based on such evaluation; and




d)  Disclosed
      in this report any change in the small business issuer’s internal control over financial
      reporting that occurred during the small business issuer’s most recent fiscal quarter that
      has materially affected, or is reasonably likely to materially affect, the
      small business issuer’s internal control over financial reporting;




5.  The
      small business issuer's other certifying officer(s) and I have disclosed, based on our
      most
      recent evaluation of internal control over financial reporting, to the
      small business issuer's auditors and the audit committee of the small business issuer's board of
      directors (or persons performing the equivalent functions):




a)  All
      significant deficiencies and material weaknesses in the design or operation
      of
      internal control over financial reporting which are reasonably likely to
      adversely affect the small business issuer's ability to record, process, summarize and
      report financial information; and




b)  any
      fraud, whether or not material, that involves management or other employees
      who
      have a significant role in the small business issuer’s internal controls over financial
      reporting.
