First - This is an antenna/ counterpoise that I’ve only read about, haven’t tried it yet in practice.
About 10-15 years back, I saw an article in a ham magazine (can’t remember which one) that describes an antenna (dipole and vertical wire/counterpoise) made from antenna rotator cable (I think 7 or 8 conductor).
The different wires in the rotator cable were trimmed for different freqs and tuned for the center of the specific freq ranges needed. The wires were not pulled apart from the single rotator cable section, cuts were made at different required lengths. When used as a dipole or vertical/counterpoise, only the two pre-cut sections of rotator cable were needed for multi-band operation.
When used as a vertical/sloper wire with counterpoise, the individual wires in the cable section may have needed retrimming for this configuration; in both the radiator and the counterpoise.
Never got to try it, as usual life intervened. It’s still in the radio plans section of the brain, just needs to be executed. The author did mention that the antenna worked for him with no tuner, but I don’t know about any interaction between the individual conductors; nor the radiation efficiency/pattern.
This MAY work for using a single counterpoise or radiator or both when using a dipole or vertical, but may need a small tuner (ZM-2, SOTA Tuner, SOTABEAMS, etc. ) depending on the current configuration as dictated by available supports. May be useful if the desired radiation direction is in one direction. Or a few rotator cable counterpoise wires could be cut/trimmed to the desired lengths and spread out in different directions.
Again, I haven’t tried this one. Hopefully someone on here may have tried it and can pass more info. It does have the advantage of multiple cut lengths, but is only one physical wire if used as a single wire counterpoise.
