VHF ou UHF - Quelle est la bande de fréquence appropriée

que dois je choisir suivant mon utilisation ?

Les radios sont disponibles avec différentes bandes de fréquences. Pour les radios PMR et les radios non-professionnel le choix se fait entre les fréquences VHF et UHF.


  • VHF: 136-174 MHz
  • UHF: 403-470 MHz


Grosso modo, la bande VHF est faite pour une utilisation en terrain ouvert c'est à dire en Extérieur et la bande UHF est à privilégier pour un usage en terrain fermé, c'est à dire en Intérieur dans les Bâtiments.

Si les deux domaines sont couverts Intérieur / Extérieur ou que les dispositifs doivent travailler dans des environnements avec des obstacles ou du béton armé - avec des étages, comme les garages ou les boîtes de nuit Discothèques - il est recommandé d'utiliser la Bande UHF.


Sachez qu'un accord de votre antenne surtout en UHF sur la fréquence principalement utilisée améliore énormément l'émission / réception.

VHF ou UHF - Alors vous avez choisi la bonne Bande de fréquences ?

Un petit truc pour se souvenir on peut Voir donc V comme VHF.

    Very impressive! I appreciate your post. To find the stuck pixel, you can do a Dead Pixel test by running your display in full-screen mode through a colour wheel or in black and white. To achieve this, wipe your screen with a soft cloth and then launch your browser to the Dead Pixels Test page.

    A lot of writers recommend just writing and composing no matter how bad and if the story is going to develop, you’ll suddenly hit “the zone” and it’ll develop. walking dead Jacket
