excellente antenne

Cette antenne est excellente pour quelqu'un qui ne veut pas se prendre la tête, j'en utilise une depuis 20 ans, (fabrication maison, car vu le prix pour quelques bouts de fils !) Mais comme toute antenne qui fait tout, elle est moins bonne qu'un multi-doublets taillé précisément pour chaque bandes choisies, moi, elle ne s'accorde pas du tout sur 10m, pare-contre elle s'accorde sur 160m. mais avec un rendement minimum, 73s à tous !!

tres bonne en reception uniquement..

ATTENTION l'antenne est très bonne en réception uniquement en émission il y a beaucoup de tos et impossible de calibrer l'antenne avec une boite accord je la recommande pour la réception uniquement.

Answer:

Merci de votre retour d'expérience, toutefois cette antenne fonctionne parfaitement en émission et avec un tuner automatique comme pour toutes les G5RV.

Pour fonctionner correctement en émission, cette antenne doit être installée en respectant plusieurs critères :

- Le sommet de l'antenne doit être à 7m minimum au dessus du sol, 10m étant recommandé
- L'antenne doit être montée soit en position horizontale et elle est dans ce cas directionnelle, soit en V inversé et elle est alors omnidirectionnelle, en respectant un angle compris entre 90° minimum et 120° maximum,
- Le câble coaxial ruban doit être tenu verticalement et éloigné de tout support métallique

Sans le respect de ces contraintes, l'antenne aura du ROS.
