Les deux stubs<\/strong> — 10cm et 5cm — Situ\u00e9s sur l’isolateur de gauche
\ndu dessin sont pr\u00e9vus pour le r\u00e9glage final. Celui du haut pour

Cpole<\/strong> 14 mhz maison… Stub, r\u00e9glage en qq minutes \u00e0 l’aide du MFJ259.
\nBase de l’antenne Cpole 14mhz, le choke 1\/1 fait merveille…
\n1\/2 de Ros sur toute la bande ..
\nApr\u00e8s plusieurs essais une position \u00e0 40, 50<\/strong> cm sol maximum est la plus efficace et \u00e9vite les coups de Ros intempestifs, possibilit\u00e9 de poser au sol quelques radians en croix et non rattach\u00e9s \u00e0 l’antenne ( Plan de sol \u00ab\u00a0simple\u00a0\u00bb)<\/p>\n

Pr\u00e9voir une longueur plus grande de fil \u00e0 la construction, ou de rallonger les \u00e9l\u00e9ments si vous \u00e9levez la C-pole.. Des essais faits avec le Balun sur Tore, \u00a0d\u00e9taill\u00e9 ci dessus, sont positifs.<\/p>\n
