6 Antenna Siting

  6.1 It is desirable that the antenna be sited in such a position that no obstacles likely significantly to degrade the performance of the equipment appear in any azimuth down to an angle of elevation of -5.

  6.2 The sitting of the antenna needs careful consideration, taking into account the adverse effect of high levels of vibration which might be introduced by the use of a tall mast and the need to minimize shadow sectors. Objects, especially those within 10 m of the radome which cause a shadow sector of greater than 6, are likely significantly to degrade the performance of the equipment.

  6.3 The above-deck equipment should be separated, as far as is practicable, from the antennae of other communication and navigation equipment.
