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
It's called a Wilkinson splitter. Here is a link to some of
the theory.
I don't think it's fair to call it a Wilkinson without a resistor across the
output ports. A real Wilkinson provides port-to-port isolation due to the
addition of the resistor. A tee and 75 ohm cables doesn't provide
You can handle the impedance matching by using 1/4 wave
