<p>Boa tarde.<br />
Bonito projecto. Estou para começar de trabalhar uma parecida. Essa só tem um problema: é que para receber e transmitir tem que haver um cabo coaxial ligando o transceptor á antena e essa não tem, eh eh eh.<br />
Bem haja aos colegas que fazem essas experiencias e as compartilham comnosco.<br />
Terminei um projecto de uma antena para os 6mt. Conto logo quando chegar a casa montá-la no suporte. Assim que estiver montada enviarei tambem fotografias<br />
Cordiais cumprimentos<br />

<p><font size="2"><font face="Verdana" size="3">O desafio tinha sido lançado por mim ao colega Arsénio Balola, CT1EWH, ao invés das suas já famosas chaves de morse, desta vez era construir uma antena J Dual-band portátil, numa tarde, a partir de um desenho já publicado na Lista ARLA/CLUSTER.<br />
<br />
O resultado, se me permitem, espectacular, foi aquilo que o construtor chamou " Antena J de campanhã " e eis aqui as fotos da sua montagem:</font><br />
