Abstract: The present invention relates to a clamp (1) for clamping or bracing high-frequency cables (2 and/or 3). The clamp (1) comprises an indicating device (21) that determines whether a spring (12) on the clamp (1) has been brought to exert the desired pressure or tensional force during assembly and maintain said desired pressure or tensional force thereafter.

Abstract: The present invention relates to a device for grounding feed or supply cables between transmitters or receivers and antennas or aerials, whereby at least one connector, through an aperture in the outer sheath of the supply cable, is in contact with an exposed portion of an inner conductor of the supply cable for grounding the inner conductor through at least one ground wire cooperating with the connector.

Abstract: The invention relates to a device at antenna systems for generating radio waves, including a supporting structure mounting at least one main radiator (3) for transmitting radio waves and where high frequency electric currents are generated in the supporting structure when the main radiator (3) is transmitting the radio waves. In order to improve the range of the main radiator (3) and at the same time reduce its backward radiation, the supporting structure includes a secondary radiator (14) for each main radiator (3). The secondary radiator (14) has at least one break portion (12) for interrupting or breaking the high frequency currents generated therein and through the thereby interrupted flow of the high frequency currents in the supporting structure reduce deviations from the desired range and/or direction of the radio waves transmitted by the main radiator (3).
