MFJ-1046 PASSIVE PRESELECTOR
Introduction
The MFJ-1046 Passive Preselector is designed to reduce receive overload from
strong out of band signals. It contains selective circuits that cover 1.6 to 33
MHz in six steps, providing the greatest selectivity on the lowest frequencies
where overload is most common.
The MFJ-1046 has two rear panel SO-239 connectors for RF connections and a
bypass switch to take the unit in and out of the circuit.
Installation
Connect the MFJ-1046 Passive Preselector between your antenna and receiver as
shown in Figure 1. The
