Questions
| Michel on 2020-04-27 | Question: Cette antenne peut-elle convenir pour ce TX Yaesu FT-818 ND ? |
Answer: L'antenne ATAS-120 ne fonctionne pas avec le FT-818 qui ne pourra pas piloter le réglage automatique de l'antenne. | |
| Maurice on 2020-04-10 | Question: Faut-il un cordon d'alimentation particulier pour piloter le réglage de cette antenne avec un Yaesu FT-450D ou le simple branchement de cette antenne sur la prise "antenne " du TRX suffit à l'alimenter ? |
Answer: L'antenne motorisée ATAS-120 est bien directement compatible avec le Yaesu FT-450D qui envoi les signaux de commande via le câble coaxial pour régler et alimenter le moteur interne de l’antenne ATAS-120 qui ajuste la longueur de l’élément rayonnant afin d'optimiser automatiquement le SWR sur les bandes 7/14/21/28/50/144/430 MHz. | |
