Five possible sites were studied for placement of 2-30 MHz twin-whip antennas on the deck edge of ships of the CVA 59 to CVAN 68 types. Performance of the antennas under various operating conditions was measured computer techniques permitted the storage, reduction, and tabulation of the data to facilitate comparison. It was found that siting of the antennas did not appreciably affect their performance, provided they were more than quarter wavelength at 2 MHz, approximately equal to 125 feet from the forward and after ends of the flight deck and from the island. In pairing the antennas to achieve space diversity, the most important factor is the distance between them, which should be at least 200 feet. Author
