Summary
[edit]DescriptionAntenne quad UHF TNT.jpg |
Français : Antenne maison ( bricolée pour les "nuls") type biquad pour la réception de la gamme UHF c 21 à 69 (vue ici en polarisation horizontale habituelle), application usuelle TNT, appartement ou grenier.(si champ électromagnétique suffisant, environ 75 dBµV/m )
Le réflecteur (arrière) est fait d'une plaque de tôle récupérée de 31 cm sur 50 cm, et le rideau quad avec du fil de cuivre du câble coaxial dénudé. Un départ d'angle est soudé sur la tresse et l'autre sur l'âme du coaxial, habituel. La distance séparant le rideau à la plaque est ici de 16 cm. Tous les côtés du cadre font ici < 16 cm,= c 21. Note : les 2 quadrilatères peuvent remplacés par une biboucle de même longueur déployée, soit un diamètre de boucle de 19.7 cm. Malgré une réalisation, sans soucis d'esthetisme, cette antenne "TNT" simple est efficace et performante par rapport à son encombrement. Durée de la réalisation < 15 mm. |
