There are two types of "passive" splitter:

a) resistive (6dB loss, 6dB isolation between outputs), and

b) hybrid, about 3dB loss input-to-each-output, c 20dB isolation between outputs (minimises any LO leakage from one tuner getting into the input of the other).

Normally the hybrid designs are broadband, have f connectors and are housed in die-cast zinc cases.
