I am a bit puzzled ..the Sirio Megawatt 4000 is a 11m mobile antenna ..its 6feet 6inch long and base loaded ..however, Sirio gives it out as a 7/8 wave ,, well i know a 1/4 wave don't need a matching device and a 7/8 wave will need one ..but the Sirio don't need one which would lead me to believe its at least pretending to be a 1/4 wave ...so how do Sirio call it a 7/8 wave and what is it really ??..if i had to guess i would say its a 1/4 wave that's been shortened and had a coil/inductor added to compensate the missing length but is it not still a 1/4 wave as it don't need a matching device
