Abstract

Sender/mottakeranlegg (l) med en senderdel (3, 6) og en mottakerdel (4, 7, 8) med sin respektive sender (3) og mottaker (4), Anlegget fremviser liten endring av innskuddsdempningen mellom en felles antenne (2) og senderdelen hhv mottakerdelen, som funksjon av senderef- fekten, og anlegget har ikke behov for noe batteri med tilhørende strøm- regulator for å gi omkoplingsstrøm for omkoplingen mellom sending og mottaking. Derved oppnås bedring av effektvirk- ningsgraden og reduksjon av fremstil- lingskostnadene. En sirkulator (9) er på vanlig måte anordnet i et grenpunkt A mellom sender- og mottakerdelen, og en omkopler (10) er innskutt mellom sirkulatoren og mot- takerdelen for automatisk kopling av sirkulatorens mottakerutgang til en belastningsmotstand (11) når senderdelen er aktivert. Mottakerdelen skilles der- ved automatisk fra senderdelen og anten- nen under sending, og det er effekten fra senderdelen som automatisk bevirker omkoplingen.
