This is simply 4-way analog splitter. Designed for no-delay PTT switching. From one input to four outputs. You can split PTT signal to four independent devices.
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 simply K9AY feeder box with direction switch, variable and fixed Rload and protections. Coaxial output has got common-mode current filter.
This K9AY one direction is ideal for SO2R and Multi/Multi. Sharing one direction into more receivers. Also easy to phasing it into the array.
This one coax output beverage antenna has got internal relay for direction switching.
This two coax output beverage antenna has got two output connectors with opposite directions at the same time. It is ideal for SO2R or MM as antenna direction sharing.
This is 2 element beverage antenna array. In this End-Fire array the beverage antennas are very close to each other. Usually 2 to 6 meters. One beverage is shifted to front by the stagger distance. This array needs...
A bias tee is used to insert AC or DC power into an HF signal to power remote antenna preamplifiers (DC), Bi-directional beverages (AC) or other devices.
