rough drawing: (hope it can be deciphered)

                     10.0deg (orient)

                       TWR#1

                 105.0deg (spacing)

                                           70.0deg (orient)
                                   TWR#2

                           10.5deg (spacing)
                     ref

              105.0deg (spacing)

                 TWR#3

            190.0deg (orient)

There is no actual tower at the reference location.
