The splitter or combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads.
Assembled
The RX small preamp is very simply low noise preamplifier module with 2SC5551 transistor based on W7IUV design. Use it as high IP preamplifier for RX antennas, buffer amplifier or small driver.
Common mode choke coils work as a simple wire against differential mode current (signal), while they work as an inductor against common mode current (noise).
This is two port antenna switch - middle box between pair of Bi-Directional antennas with single coax output.
