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

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
sections of 75 ohm
coax between the receiver input and the T. The 1/4 wave 75
ohm section
steps the 50 ohm receiver input impedance up to 100 at the
other end, two
of those in parallel at the T gets you back to 50 to match
the
If you use any of the below listed devices, you'd
better chuck the pre-selector (rx-filter) and
put something better in front of the preamp.
Been there, done that, coffee mug and tee-shirt.

The below is an old Decibel Products method

Tx Combiners. I have one here... along with
some very limited paperwork on it.
