Summary form only given, as follows. A.R. Giddis and R.B. Barrar, authors of "An Improved Ground Beacon Antenna," which appeared on pp. 315-323 of the December, 1963, issue of these Transactions, have called the following to the attention of the Editor: 1) The argument of the J9 function in the second term of (6), on page 318, should be enclosed with an "open" parenthesis, i.e., J9(kd9). 2) The lower angular limit of the upper exponential function in (17), on page 320, should read θ1, i.e., θl is greater than or equal to θ is greater than or equal to θ0. The sense of the presentation is not compromised by these errors which should become evident to the reader.
