RX distribution amp for a Mini Whip
 

Going to the trouble and inconvenience of installing
a Mini Whip at the bottom of the garden (120 feet away
at the edge of the cemetery) it would make sense for all
the RXs in the receiver farm to be fed from this one antenna.

Can anybody point me to a design for an aperiodic distribution amp to
take a single 50 ohm in and to fan out to multiple 50 ohm
outputs with isolation between the outputs and 0dB gain
to maintain the high claimed IP3?

TIA
