Abstract: The invention relates to a jammer antenna system having a main plate, the main plate being substantially horizontally oriented during use of the jammer antenna system, a horizontal antenna provided in the main plate and arranged for radiating horizontally polarized radiation; first vertical antenna removably attached to the main plate; and at least one second vertical antenna removably attached to the main plate for radiating vertically polarized radiation. The invention proposes to provide a first vertical antenna, the horizontal antenna, and the second vertical antenna being electrically decoupled, such that removing one of the vertical antennas does substantially not change a horizontal antenna intrinsic impedance of the horizontal antenna or a first vertical antenna intrinsic impedance of the first vertical antenna.

Abstract: In a method, a computer program and a system for carrying out a project from a plurality of differently located electronic data processing (EDP) devices, which are connected via a data network with a main server serving the central data loading for the purpose of data exchange and whereby, during individual working time intervals, respectively one other from the plurality of EDP devices for carrying out the project is at least partially activated. A method, computer program and system provide that employees at other sites, located at a distance from the main server, are permitted full cooperation in a project. The data network is configured in a cross-locational manner, and that the individual EDP devices are located distributed at least partially in a cross-locational manner.

Abstract: The invention relates to a method, a computer program and a system for carrying out a project from a plurality of differently located electronic data processing (EDP) devices (200′, 300), which are connected via a data network (400) with a main server (100) serving the central data loading for the purpose of data exchange and whereby, during individual working time intervals, respectively one other from the plurality of EDP devices (200′, 300) for carrying out the project is at least partially activated. Proceeding from this prior art, the aim of the invention is to develop a known method, computer program and system of the stated kind in such a way that employees at other sites, lying at a distance from the main server, are permitted full cooperation in a project.
