Title:
Directive Antenna System in the 6 to 15 MC Band for Essex Class Aircraft Carriers
Report Date:
1946-07-10
Abstract:
This report describes a directive antenna system developed by the Naval Research Laboratory for use in conjunction with the Blanket system of communication in the 6 to 15 Mc band on Essex-class aircraft carriers. Radiation-pattern measurements conducted with this directive antenna installed on the starboard side of an Essex-class carrier (CV-39) have demonstrated that the proposed antenna system has the desired characteristics and fulfills the problem requirements. The radiation patterns indicate beam widths in the order of 50 to 60 degrees for ionosphere transmission and 65 to 8- degrees for free-space transmission; front-to-back field strength ratios greater than 3 to 1 are also indicated over the specified frequency range. The antenna system can be energized by standard Navy-type transmitters such as the Model TBK series, and offers no interference to topside fighting equipment.
