The increasing use of radio by ships has led to a corresponding growth in the number and type of aerials carried and an extension of the frequency range covered. These aerials must be accommodated in a much reduced area in the absence of traditional supporting masts and yet are expected to give high performance without greatly increased cost. This paper examines some of the installation problems related to the restrictions of the aerial site and the environment. Advances in the design of receiving, and transmitting aerials are discussed. While for transmitting aerials it appears unlikely that there will ever be an economic design capable of offering good performance on both the statutory 405 to 525 kHz band and the optional 4-25 MHz band, there have been significant improvments in the design of active receiving aerials. The paper concludes with a consideration of the effects of environment, i.e. temperature, corrosion, vibration, motion stress and wind-loading on ship-mounted aerials. Order from: BSRA as No. 46,730.
