LNB duplo

Ola a todos
Agradeço uma informaçao simples:um lnb duplo funciona como 2 lnb independentes,ou como 1 lnb com 2 saidas?Há alimentaçao independente para cada saída ou comum?Quer dizer se houver corrente no lnb as duas saidas estao activas ou pode uma delas estar sem alimentaçao?
Obrigado

Boas,
pela tua pergunta, suponho que te referes a um LNB "Twin", o que equivale a ter 2 LNB,s Universais totalmente independentes. As alimentações também são independentes.

um LNB duplo (ou twin) é um LNB com duas saídas, tem dois converters e dois prés, o que significa que se comporta como dois lnb's e ambas as "saídas" têm que estar alimentadas, servem para alimentar dois decos com o mesmo sinal (mesmo sat).
um LNB Monobloco são dois lnb's na mesma estrutura e servem para a captação de dois satélites que estejam em azimutes muito próximos usando a mesma parabólica.
