| Zusammenfassung: | The wire aerial, for radio transmitters, has its wires suspended between two vertical towers mounted on a rotatable base. The aerial can be rotated about a vertical axis passing through its centre. The bearing is located beneath the aerial's centre of gravity. The drive is situated between the bearing's rotor and stator. The stator or rotor is provided with a scale showing the angle of rotation. The advantage lies in low cost. |
