| Description |
Français : Avion F-AOHB. Avant les années 1970, les communications aéronautiques en radiotélégraphie étaient dans la bande comprise de 325 kHz à 405 kHz. En vol une antenne pendante B longue de 120 mètres à 450 mètres était déroulée pour établir les communications radios. Proche du sol cette antenne B est rembobinée sur un touret à manivelle. À l'extrémité de l'antenne pendante un plomb de lestage C porte l'indicatifs radio de l'aéronef. Et l'antenne fixe A sur le fuselage est utilisé en permanence.
English: Aircraft F-AOHB. Before the 1970s, aeronautical communications in radiotelegraphy were in the band from 325 kHz to 405 kHz. In flight, a pendant antenna B 120 meters long at 450 meters was unrolled to establish radio communications. Near the ground this antenna B is rewound on a crank reel. At the end of the hanging antenna, a ballast lead C bears the radio call sign of the aircraft. And the fixed antenna A on the fuselage is used permanently.
