Isihlanganisi se-L-band iyisisetshenziswa se-elekthronikhi esihlanganisa amasiginali amaningi kububanzi befrikhwensi ye-L-band. Yaziwa nangokuthi isihlanganisi sefrikhwensi ye-wideband. Isihlanganisi se-L-band sibalulekile esiteshini sokusakaza ngoba siwucezu lwemishini evumela ama-transmitters amaningi ukuthi axhunywe ku-antenna evamile yokusakaza. Ngaphandle kwesihlanganisi se-L-band, ama-transmitter ngeke akwazi ukuxhunywa ndawonye, futhi isiteshi sokusakaza ngeke sikwazi ukusebenza. Ngakho-ke, isihlanganisi se-L-band siyadingeka esiteshini sokusakaza.
