    摘要： Bei einer Antennensteckdose mit zwei Eingängen (E1, E2) und vier Teilnehmeranschlüssen (T1...T4) ist dem ersten Eingang (E1) ein Zweifachverteiler (ZV) nachgeschaltet, dessen erster Ausgang (A1) über einen Bandpaß (BP) und eine Bandsperre (BS) für UKW mit dem dritten und vierten Teilnehmeranschluß (T3, T4) zum Empfang des terrestrischen TV- und UKW-Bereichs verbunden ist und dessen zweiter Ausgang (A2) zugleich mit dem zugehörigen ersten Teilnehmeranschluß (T1) und über einen Tiefpaß (TP) mit dem am zweiten Eingang (E2) angeschlossenen zweiten Teilnehmeranschluß (T2) verbunden ist. Dabei liegt die Grenzfrequenz des Tiefpasses (TP) oberhalb der höchsten, am zweiten Teilnehmeranschluß (T2) bei leerlaufendem zweiten Eingang (E2) übertragenen Signalfrequenz und unterhalb der niedrigsten am ersten Teilnehmeranschluß (T1) übertragenen Signalfrequenz. Durch diese kostengünstige schaltungstechnische Maßnahme sind die vier Teilnehmer-anschlüsse (T1...T4) nicht nur bei einem Einsatz der Antennensteckdose in Zweikabel-Verteilnetzen belegbar, sondern auch bei Verwendung in BK-Netzen, deren einziges Signalübertragungskabel am ersten Eingang (E1) angeschlossen ist (der zweite Eingang (E2) läuft leer).
    Diese Universal-Antennensteckdose ist darüber hinaus kostengünstig und vereinfacht den praktischen Einsatz durch den Installateur. Ausgestaltungen der Antennensteckdose für einen störungsfreien Empfang sind angegeben.

    摘要： An insertion system of power supply and/or control voltages, deriving from a power supply and/or control box, in a coaxial cable for radio-frequency, comprising an injector or R.F. fitter (10), equipped with plugs (2) and (3) or clamps, which is applied in series at any point on the coaxial cable (9) included between a receiver (13) and an amplifier, selectors, converter, and/or aerial directional devices and the like. The injector (10) is coupled to a control and/or power supply box (1) by means of a simple bipolar conductor (8) through which transit only the control and/or power supply voltages, either in the form of continuous signals, or in the form of possible continuous or alternating power supply voltages, coupled or not to pulsed control voltages or with pulse trains overlapping the power supply voltages, coded or not, which may be used for other purposes.

    摘要： The present invention discloses an input/output apparatus of a multiplexer, including: a main tap and at least two branch taps of the main tap, where each of the at least two branch taps is configured to couple to a different resonant cavity in the multiplexer, and the at least two branch taps include a first branch tap and a second branch tap; a coupling polarity of the first branch tap is opposite to that of the second branch tap; and a coupling calculation frequency of the second branch tap is closest to a coupling calculation frequency of the first branch tap. The input/output apparatus of the multiplexer provided in embodiments of the present invention enables two channels with closest frequencies to use different coupling polarities. Because the coupling polarities are different, signals naturally do not interfere with each other, and signal interference between channels is eliminated in principle. The embodiments of the present invention further provide a corresponding multiplexer.

    摘要： A feed network for use with an antenna array includes at least first and second RF inputs, a combiner network and a beamforming network. In some examples, additional RF inputs are provided. Each RF input corresponds to a sub-band. The first RF input for a first sub-band signal is coupled to a first sub-band parameter control; the second RF input for the second sub-band signal is coupled to a second sub-band parameter control. The combiner network is coupled to the first sub-band parameter control and to the second sub-band parameter control. The combiner network also has at least one output comprising a combination of the first sub-band signal and the second sub-band signal. The beamforming network is coupled to the combiner network and has a plurality of RF outputs. The first and second sub-band parameter controls are independently adjustable. In one example, the beamforming network comprises a Butler matrix.
