Receiving Antenna Group Design for 2-30-MHz Operation (Redesign of the AN/SRA-43 Provides Extended Frequency Coverage).
Abstract
A minimal redesign of the present AN/SRA-43 provides a suitable backup shipboard receive antenna for 2-30-MHz operation. On the basis of quasi-minimum shipboard noise levels, the efficiency of the antenna group over a ground plane is judged adequate (except for a 2-dB deficiency between 16 and 17 MHz). Pattern data taken on a model basis show that (1) efficiency on a mast will be a function of mounting height; (2) an untuned antenna mounted horizontally from a ship's mast will show lobing at frequencies above 6 MHz; and (3) there will be less pattern lobing and better low-angle coverage when the antenna is removed from the mast structure and vertically oriented.
