Logperiodinen antenni

Antenni on radiolaitteiston osa, jota käytetään lähettämään ja vastaanottamaan sähkömagneettisia aaltoja (radioaaltoja). Lähettävä antenni muuntaa lähettimeltä tulevan suurtaajuisen vaihtosähkön sähkömagneettiseksi säteilyksi A log-periodic antenna (LP), also known as a log-periodic array or log-periodic aerial, is a multi-element, directional antenna designed to operate over a wide band of frequencies. It was invented by Dwight Isbell and Raymond DuHamel at the University of Illinois in 1958

The log periodic antenna or aerial often called the LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies Resources listed under Log Periodic Antenna category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators
