But only the header in your code? In your question you can’t see where or how you are using your header... I don’t think you need JS or jQuery for that, with CSS and position:Ticky you solve!

Ana, welcome to Stack Overflow!

I tweaked your code a little bit and it was like this, put it to rotate here and give a little look to see if it answers:

<!DOCTYPE html>
    <html>
      <head>

        <style>
          #cabecalho {
            background-color: #b5e61d;
            font-weight: bold;
            padding: 7px;
            margin-bottom: 5%;
            text-align: center;
          }
          #banner {
            position: absolute;
            top: 5px;
            right: 10px;
            width: 110px; height: 300px;
            margin-top: 50px;
            background-color: red;
            border: 5px solid #000;
          }
          #footer { 
            padding: 10px; 
            background: #b5e61d; 
            font-weight: bold;
            text-align: center;
          }
        </style>

        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
        <script>
      jQuery(document).ready(function() {
        $(window).scroll(function () {
          var scroll_top = $(document).scrollTop();
          var footer_top = $('#footer').offset().top;
          var banner_heigth = $('#banner').height();
          var set = scroll_top + "px";
          if ((scroll_top + banner_heigth) >= footer_top) { 
            set = (footer_top - banner_heigth*1.3) + "px";
          } 

          jQuery('#banner').animate({
              top:set
            },
            {
              duration:1000,
              queue:false
            });
        });
      });
    </script>

      </head>
      <body>

        <nav id="cabecalho"> HEADER </nav>
        <div style="height:1200px">
          Conteúdo da página                
        </div>
        <div id="banner">
          <div class="bannerconteudo">BANNER</div>        
        </div>
        <div id="footer"> FOOTER </div>
