Abstract

Det er beskrevet en antenne som er kombinert med et rotorblad (101) for et helikopter. Antennen omfatter et eller flere elektrisk ikke ledende rotorblader (101), hver med en elektrisk leder (210,310) anbragt parallelt med hovedaksen for et tilhørende rotorblad (101). En forbindelsesanordning (410,412,510,521,620,623) forbinder antennen med utstyret for mottagning og sending av radiobølger som befinner seg i skroget (102). Det er også beskrevet et kommunikasjonssystem som innbefatter utstyr for sending eller mottagning av radiobølger. Det er videre beskrevet en retningantenne og rotorblad (101) for et helikopter (100). Antennen omfatter tre eller flere elektrisk ikke-ledende rotorblader (200), hver.-med en elektrisk leder (210) anbragt parallelt med hovedaksen for et tilhørende rotorblad (200). To av de elektriske ledere (210) med vinkelstillinger nærmest en på forhånd bestemt vinkelstllllng blir med koplingsan- ordninger (1100) forbundet med utstyret til sending .eller mottagning av radiobølger. De gjenværende ledere kan enten være koplet til helikopterets skrog eller :tilført et signal ute av fase sammenlignet med det som tilføres de to elektriske ledere. Det er også beskrevet kommunikasjonssystem med utstyr for 'sending eller lmottagning av radiobølger.
