pm_4o3a_ps3000rx_splitter

The PS-3000RX power splitter from 4O3A can be used to split power between one, two or three antennas/directions or to combine two or three antennas.


It can be used broadband in the shortwave spectrum from 2 - 30 MHz and has excellent matching with sophisticated circuitry.


The PS-3000RX can be controlled with the Station Genius, any manual switching controller that provides +12V DC for antenna selection, or a SPLIT relay that inserts a 50-to-22-ohm transformer for matching two or three antennas.


The splitter has a unique feature - the "RX AUX" auxiliary output. This is an output to which all unused antennas are switched. This is advantageous when two operators are listening on the same frequency with antennas pointed in different directions. On a radio with two built-in receivers, the second receiver should simply be connected to the RX AUX output. The second receiver will then have all antennas not selected by the primary user.


If two radios are listening on the same frequency, both radios MUST block the RX AUX output on the Power Splitter with a PTT signal (GND). To do this, simply connect the "PTT IN" RCA connector on the PS-3000RX to a PTT output on your equipment, such as APM, USB Keyer or Station Genius. The PTT signal is used to connect the RX AUX output to ground to protect the second receiver.


The power splitter is broadband - it does not rely on 1/4-wave phase lines for antenna matching. A combination of different antennas can be used for different transmit and receive modes, such as a Yagi and a vertical antenna.


Power handling: Maximum 3 kW (CW)
