Germeshausen and Grier, Inc., Boston, MA 661202 Confidential Results are presented of communication studies on the Cutlass/Roundup mission conducted on 23 November 1965. The possible interference between EG&G and Sandia Communication links tentatively established for Bass Drum was determined to be zero. The Bass Drum communication data link configuration is thus deemed to be acceptable as conceived. As a secondary Cutlass objective, field strength measurements on the assigned Bass Drum frequencies were made and analyzed. Results are given of the analysis of these measurements on the nine orbits flown by the three NC-135 aircraft in the area of the Cutlass Zero-site barge. The Cutlass experiment showed that the radiating lobes of the barge antenna extended fifty to sixty miles and that usable Signals can be received at both the barge and the aircraft provided (1) receiver sensitivity is 10 {mu}V or greater, (2) transmitter outpower is 25 W or greater on the barge and 20 W or greater on the aircraft, and (3) aircraft altitude is maintained above 5,000 ft. The most critical requisites for reliable reception, in the order of their importance, are (1) antenna-to-antenna unobstructed signal path, (2) aircraft altitude (as directly related to the lobe pattern), (3) transmitting antenna stability or predictable orientation, and (4) 801.
