The UWBA functioning mode is the reception and radiation of the electromagnetic waves by antenna with a circular antenna pattern in motion and on the parking of the vehicle, where it is installed.
The basic functional feature of the UWBA is the reception and radiation of the electromagnetic waves in ultra wide frequency band without retuning of UWBA.
The various versions of UWBA (UWBA1 or UWBA2) can be used by civilian agencies, as well as the army, security services, police, border guards and other power structures and organizations.
