L'antenne « log periodic », ou en français « log périodique », couvre une large gamme de fréquences avec les avantages d'une antenne directive et… un peu de gain qui, sans atteindre celui d'une antenne yagi de même lon-gueur, taillée sur la bonne bande, reste malgré tout satis-faisant. Ce type d'antenne se compose d'une suite de dou-blets alimentés par une ligne qui s'inverse à chaque élément. En VHF, c'est souvent un double boom qui fait office de ligne d'alimentation. L'antenne de WiMo ne déroge pas à cette règle. La longueur des élé-ments décroît régulièrement, suivant un facteur constant, leur espacement également. Si, comme c'est ici le cas, l'an-tenne possède 24 éléments, seuls quelques-uns sont impli-qués dans le fonctionnement sur une fréquence donnée, d'où un gain inférieur à celui Vous n'avez pas beaucoup de place pour installer une antenne et vous aimeriez couvrir des VHF aux SHF ? Pas facile, hein ? Pourtant, il existe une solution : l'antenne « log periodic » et plus particulièrement ce modèle fabriqué par WiMo et distri-bué en France par Infracom. beaucoup moins directive mais dans cette configuration, il était intéressant de disposer d'une antenne que l'on puisse pointer directement (site et azimut) sur le satellite sans aucun moteur. La réalisation de l'antenne est sérieuse. Chaque élément en tube alu est fileté à son extré-mité et passe à travers le boom (constitué d'alu à section car-rée). Une rondelle et un écrou assurent le serrage. La photo d'illustration parle plus qu'un long discours. Le connecteur est une prise N. Placé à l'avant de l'antenne et sur la partie inférieure, il permet au coaxial de longer la jambe de force et d'être maintenu en place par des colliers. Le poids n'excède pas 2 kg, ce qui autorise le montage sur des mâts type « télévision ». La pièce de fixa-tion au mât est fournie, elle permet une légère inclinaison de l'antenne si souhaité. A sa partie la plus large, l'an-que procurerait une yagi. WiMo annonce un gain moyen de 8 dBd pour cette antenne.
