Коллеги, кто понимает в антеннах, просветите…
В эпоху цифрового ТВ на крышах раплодились индивидуальные антенны вот такой конструкции
Откуда у них (без усилителя) заявленный коэф.усиления 20дб ?
Как у классического “волнового канала” втрое или вчетверо большей длины ?
Может кто-то пробовал измерять реальный сигнал с такой антенны прибором, потихоньку отрывая торчащие элементы, пока только одна петля не останется, и узнать что меняется?
Переправил вопрос на форум прорадио.
Может кто откликнется
