Phase 1 : II pose à terre le carquois de l'antenne. Il règle le trépied pour assurer la hauteur et la planéité du carquois ceci à l'aide d'un niveau à bulle intégré sur le dessus du carquois.Phase 1: He places the quiver of the antenna on the ground. It adjusts the tripod to ensure the height and flatness of the quiver with a built-in bubble level on the top of the quiver.
Phase 2 : II déverrouille le couvercle du carquois (grenouillères), et en retire la structure gonflable de l'antenne en position repliée.Phase 2: II unlocks the quiver cover (latches), and removes the inflatable structure from the antenna in the stowed position.
Phase 3 : II retourne la structure en position haute et la verrouille dans le logement du couvercle à l'aide des grenouillères précédemment citées.Phase 3: It returns the structure in high position and locks it in the housing of the lid using the latches previously mentioned.
Phase 4 : II détache la sangle pour libérer les dipôles et les panneaux gonflables. Puis il visse une cartouche d'air dans le logement prévu à cet effet, et tire sur la cordelette de percussion (ceci comme un gilet de sauvetage). L'air libéré gonfle les panneaux et positionne les dipôles suivant des cordages de dimensionnement (ce qui devient un pentagone pour 5 dipôles). Le temps du gonflage est d'une dizaine de secondes. Puis il retire la cartouche et la remettre dans le bandeau de stockage. Le manomètre pression lui indique si la pression est correcte. Phase 5 : II prend et connecte le câble coaxial au matériel de réception et d'interception puis II reporte l'indication de la boussole vers le système d'exploitation.Phase 4: II detaches the strap to release the dipoles and inflatable panels. Then he screws an air cartridge into the housing provided for this purpose, and pulls on the percussion cord (this as a lifejacket). The released air inflates the panels and positions the dipoles along sizing lines (which becomes a pentagon for 5 dipoles). The inflation time is about ten seconds. Then he removes the cartridge and put it back in the storage banner. The pressure gauge tells him if the pressure is correct. Phase 5: II takes and connects the coaxial cable to the receiving and interception equipment and then reports the compass indication to the operating system.
L'antenne est opérationnelle.The antenna is operational.
Pour le repliement : L'opérateur effectue aussi 5 phasesFor folding: The operator also performs 5 phases
Phase 1 : II déconnecte le connecteur de liaison antenne. Il le love dans son emplacement réservé, à la base du mât centrale.Phase 1: II disconnects the antenna link connector. He loves it in his reserved place, at the base of the central mast.
Phase 2 : II tourne la manette d'air sur pompe pour vider les panneaux gonflables ( durée du vidage une dizaine de secondes). Il range chaque dipôle dans leur logement près du mât central en chassant les résidus d'air du panneau associé. Après II replie, autour du mât, les panneaux vidés de l'air en les bloquant avec la sangle centrale qui se fermera par système type velcro.Phase 2: II turns the air lever on pump to empty the inflatable panels (duration of the emptying about ten seconds). He arranges each dipole in their housing near the central mast by driving the air residues from the associated panel. After folding, around the mast, the panels emptied of air by blocking them with the central strap which will close by Velcro type system.
Phase 3 : II déverrouille le couvercle bloquant la structure gonflable en position haute (grenouillères ...), puis soulève la structure de l'antenne repliée.Phase 3: II unlocks the lid blocking the inflatable structure in high position (latches ...), then raises the structure of the antenna folded.
Phase 4 : II retourne et insère la structure en position basse dans le carquois puis verrouille le couvercle à l'aide des grenouillères.Phase 4: He returns and inserts the structure in the lower position in the quiver then locks the lid with the help of the latches.
Phase 5 : II débloque, glisse et verrouille les pieds dans les réservations du carquois.Phase 5: II unblocks, slides and locks the feet in quiver bookings.
Il repart en positionnant le carquois sur son dos.He leaves by positioning the quiver on his back.
Les phases 2 et 3 peuvent être mécanisées pour limiter les opérations manuelles, ceci lors du déploiement ou du repliement de l'antenne. Phases 2 and 3 can be mechanized to limit manual operations, when deploying or folding the antenna.
