Hi All,

So I have TiVo with dual tuner and an HD receiver and only 2 LNB fed coax cables. I'd like to be able to use a coax AB switch box connected to the HD and 2nd tuner on the TiVo so that when I'm not watching HD, my TiVo has 2 tuners connected.

I searched Radio Shack for a product like this, but couldn't find it.

2 questions:

1) Will it work?
2) Does an AB switch for coax exist?

- Thanks in advance!
