It may sound interesting (and cheap) but the reason that no one else has suggested it is because the impedance miss matches it causes. That is why you need something like a multicoupler whis is first a pre amp to keep the loss to a minimum then sends the pre amp to a splitter that maintains the 50 ohm match required by the receivers on each output port.
If this approach was workable then the cable company would NEVER buy a splitter but would buy TEEs --- In [email protected], Vincent Caruso <[EMAIL PROTECTED]> wrote: > > That sounds like an interesting solution, I would be interested in > learning more about it. > > Ralph Hogan wrote: > > Along these lines, someone on the list mentioned using coax multi-dropped > > (coax tee) off to each receiver for a voter application.
