VHF ou UHF - Quelle est la bande de fréquence appropriée pour mon usage

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.

    THE POWER OF HERBAL REMEDY TO CURE ANY HUMAN  DISEASES  It's a pleasure for me to write this testimony about how i got my Genital Herpes cured a month ago. i have been reading so many comments of some people who were cured from various diseases by Dr .Hazim, but i never believed them. I was hurt and depressed so I was too curious and wanted to try Dr. Hazim , then i contacted him through his email (usmandrhazim@gmail.com)  when i contact him, he assured me 100% that he will he cure me, i pleaded with him to help me out. My treatment was a great success, he healed me just as he promised. he sent me his medication and ask me to go for check up after 21 days of taking the medication. i agreed with him i took this medication and went for check up after 21 days of the treatment, To my greatest surprise my result came out  negative after the treatment, I'm very happy that i was cured and been  healthy again. I waited for 3 weeks to be very sure if I was completely healed before writing this testimony. I did another blood test one week ago and it was still Herpes negative. so i guess its time i recommend anyone going through Herpes, HSV-1 or HSV-2, HIV, HPV, Hepatitis B, Diabetes, Cancer, ALS  to contact this great man through his Email (usmandrhazim@gmail.com) OR add him up on whatsApp  +2349058026857 Thanks Doctor Hazim Usman
