GPS + Beidou Wektu Antena Marine Antena 38dBi
Pambuka produk
GPS + Beidou Timing antena jinis antena digunakake kanggo nampa sinyal satelit.Bisa nampa sinyal satelit RHCP ing pita frekuensi GPS L1 lan BD B1.
Antena iki nduweni fitur ing ngisor iki:
Gain dhuwur: Antena sirah jamur aktif bisa nyedhiyakake gain sinyal sing luwih dhuwur lan ningkatake kekuwatan sinyal sing lemah saka sinyal sing ditampa, saéngga nambah sensitivitas lan kualitas sinyal.
Stabilitas dhuwur: Antena dirancang kanthi stabilitas sing dhuwur lan bisa njaga kinerja sing stabil ing kahanan lingkungan sing beda.Iki tegese bisa nyedhiyakake panrima sinyal satelit sing stabil ing kabeh kahanan cuaca.
Pusat fase sing stabil banget: Antena sirah jamur aktif nduweni pusat fase sing stabil banget, yaiku, pusat fase sinyal sing ditampa tetep stabil ing sawetara wektu tartamtu.Iki penting banget kanggo aplikasi posisi lan navigasi, amarga stabilitas tengah fase langsung mengaruhi akurasi pangukuran.
