Answer:

equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.

Explanation:

The electromagnetic spectrum can be calculated with the relationship between the speed of light, its wavelength and its frequency.

c = λ f

For reasons of analysis and equipment used, it is artificially divided into ranges, with poorly defined limits and in some cases with overlaps between some.

For the case of analysis, f = 1.41 10⁹ Hz, we have the range called

* Microwave for f> 3 108 Hz to approximately f <3 1011 Hz

For the lower part of the frequency 3 10⁸ <f <3 10⁹ Hz we have UHF television channels and cell phones and military communications.

As the frequency observed by the researchers is in the UHF range, it is possible that they are using microwave equipment for communications, specifically equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.
