Re:  2,271,391 Shares of Common Stock, $1.00 Par Value Per Share

Ladies and Gentlemen:

         I am the General Counsel and Secretary of Allen Telecom Inc., a
Delaware corporation (the "Company") and have acted as counsel to the Company in
connection with the registration of 2,271,391 shares of Common Stock, $1.00 par
value per share, of the Company (the "Shares") to be sold from time to time by
the selling stockholders identified in the Company's Registration Statement on
Form S-3 filed with the Securities and Exchange Commission on the date hereof
(the "Registration Statement").

         In rendering this opinion, I have examined such documents, records, and
matters of law as I have deemed necessary for purposes of this opinion. Based
upon the foregoing and subject to the qualifications and limitations stated
herein, I am of the opinion that the Shares are duly authorized, validly issued,
fully paid, and nonassessable.

         My examination of matters of law in connection with the opinions
expressed herein has been limited to, and accordingly my opinions herein are
limited to, the General Corporation Law of the State of Delaware, including the
applicable provisions of the Delaware Constitution and the reported judicial
decisions interpreting such law. I express no opinion with respect to any other
law of the State of Delaware or any other jurisdiction.

         I hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement filed by the Company to effect registration of the Shares
under the Securities Act of 1933 (the "Act") and to the reference to me under
the caption "Legal Matters" in the Prospectus constituting a part of such
Registration Statement. In giving such consent, I do not thereby admit that I am
included in the category of persons whose consent is required under Section 7 of
the Act or the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.

                                          Very truly yours,

                                          /s/ Laura Meagher

                                          Laura Meagher
                                          General Counsel and Secretary
