This active splitter allows you to split one antenna into multiple RX. The splitter can also be used to split a reference frequency, for example 10MHz. The outputs have high isolation and minimal difference in splitting. The input includes a diode limiter and the preamp gain can be varied by an output attenuator. This 3-way active splitter…
