Sei que sou muito principiante nestas coisas, mas desconfio sempre de
antenas que envolvem resistências.
Por acaso tenho uma similar cá por casa, suporta 100W em frequencias até
uns 2GHz, com SWR sempre próximo de 1:1 e até cumpre o requisito
adicional de não necessitar de muito espaço ...
Pena o rendimento não ser grande coisa, não sei quão melhor será o dessa
antena.
73!
