It is alleged that the signal used for electromagnetic actuation (harassment) is an “ultra-wideband signal” (UWB) with energy levels that are so low that are almost indistinguishable from background noise. Such a signal is designed to not interfere with telecommunications or other spectrum services. It has also been alleged that signal intelligence analysts may miss or ignore it as they might choose to readjust spectrum analysis baseline to what appears as noise on a certain day or period of analysis. As mentioned by Wikipedia “some UWB formats (mainly pulse-based) may be made to appear like a slight rise in background noise to any receiver unaware of the signal’s complex pattern.”
An ultra-wideband signal (UWB) is a very wide signal i.e. a signal which includes a large number of frequencies or frequency bands. In other words, a signal with a large frequency range or bandwidth. By definition, it is a signal which is more than 500 MHz* wide; or more than 20% of the central frequency (whichever is the lesser). An example is provided by the video at the link https://youtu.be/tSjYVP705TU which shows a signal that is 1.6 GHz wide.

Another example is provided at the link https://youtu.be/N2tpWsAq2FA by Martin Bott who measured an ultra-wideband (UWB) RADAR signal between 6 MHz and 100 MHz with a very high pulse repetition rate of 100,000 pulses per second. (Notes: This is a shortwave signal, given that the above frequency interval belongs to shortwave radio frequencies. Martin notes that this very high pulse repetition rate makes the signal unsuitable for long-range surveillance.)

Ultra-wideband was previously known as pulse radio. Specific spectrum bands are allocated to UWB. It is used by RADAR imaging devices, such as "in-wall and through-wall detection, ground penetrating radar, medical imaging, construction and home repair imaging, mining, and surveillance devices" as mentioned by this ITU reference http://www.itu.int/dms_pubrec/itu-r/rec/sm/R-REC-SM.1755-0-200605-I!!PDF-E.pdf. The popular Walabot device (https://walabot.com/) is a UWB RADAR. (pdf Technical Brief: https://cdn.sparkfun.com/assets/learn_tutorials/7/2/4/walabot-tech-brief-416.pdf).
A UWB signal with complex structure and with energy that is so low that it is almost indistinguishable from background noise could only be detected by highly specialized analysts using very sophisticated expensive equipment (oscilloscopes and spectrum analyzers).
Also blocking such a low energy signal which additionally covers many frequency bands appears extremely difficult. Does this mean that there are no countermeasures? It is alleged that what must be blocked are the components of the complex waveform which target the frequencies of the most important signalling ions and specifically the neural signaling ions, as these are responsible for the major brain rhythms. These frequencies are in the ELF range.
If ion movements are remotely synchronized, that means that the major brain rhythms will be synchronized to those of the remote interface. This would be an important step towards obtaining control of brain function, as the brain would then become susceptible to an external signal similar to neural code.
Suggested countermeasures are of the "active" type in addition to "passive" shielding such as earthing/grounding as well as shielding material which lowers general electromagnetic exposure intensifying effects. For instance, magnetic generators such as randomly moving magnets controlled programmatically could be used. In addition to using a "random" moving/rotating function, such moving magnet countermeasures would be most effective if they generated patterns that prevented ion targeting frequencies, which are in the ELF range.
