    teoretic la una rotunda orizontala egala cu verticala deci cistig mai bun
    decit la una ovala.daca vorbim de ovale avem doua cazuri in care cele
    doua,orizontala si verticala,alterneaza ca marime.mai exact intr-un caz
    verticala este mai mare ca orizontala in timp ce in celalalt caz situatia este viceversa.sper ca am contribuit putin la fenomenul de iluminare.

    La o antena ovala de 0.8 (suport plastic in spate si sigla STRONG in fata) pot pune un suport dual feed ? Sint diferente fata de calitate a semnalului fata de cea rotunda ?

    ....normal ca poti pune dual feed.Daca antena nu este deformata si daca focarul este bine stabilit-este ok.Chestia cu plasticu' .....se refera doar la rigiditate,durabilitate in timp, si , ...la pretentiile tale.O antena care se respecta este cat se poate de rigida,suportul fiind pe masura!
