This is simply 4-way PTT sequencer, designed for PTT switching from one input to 4 outputs with different (fixed) delay.
This is simple analog 4-way combiner. There is no delay between inputs and output. Each input has its own LED indication and so does the output.
The splitter or combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads.

Beverage antennas provide one of the least expensive and most reliable ways to improve DX capabilities on the low frequencies.
This is very useful device - this is active splitter version in enclosure. It can provide equal voltages, equal current, or equal power to matched or unmatched loads. Input low noise amplifier can eliminate insertion...
This one coax output beverage antenna has got internal relay for direction switching.
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.
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...
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.
The splitter or combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads.
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.
