Não colega!


O que eles pretendem querer dizer é que existem para as duas bandas e 
não que tem duas bandas. Nós tomamos como referência a informação de que 
se é 440 e 145 é dual, o que eles querem dizer é outra coisa.
E nestes equipamentos, pelo menos por enquanto, é difícil senão 
impossível, encontramos equipamentos que façam as duas bandas. A 
explicação é simples, eles não foram feitos a pensar nos radio amadores, 
como tal nenhuma empresa iria adquirir equipamentos de duas bandas isso 
significava duas licenças.
