The AS2x2 is a 2×2 antenna switch designed to be used by 2 Radios and where they can share their antennas. A typical application could be a contest station where there are 2 radios in the same band (RUN and InBand). By default the RUN uses the main antenna and the InBand uses a far away reception antenna.

When the Inband need to make a QSO, the AS2x2 will exchange the antennas, so the InBand will use the main antenna meanwhile the RUN will use the reception antenna, so they can still listen their QRG.

If a linear amplifier is used by the RUN, the Inband can also use it for his transmission. In this case, the AS2x2 is connected between the RUN and the Linea Amplifier.

  • Conmutador de Antenas 2×2

    El conmutador AS2x2 presenta 2 entradas y 2 salidas, ideal para estaciones de concurso donde disponemos de una estación Principal (RUN) y una estación de Multiplicadores (Inband) en su misma banda. El conmutador se puede conectar entre la estación RUN y el amplificador (en caso de que se use) y la estación InBand y la antena de recepción. Tan pronto como la estación Inband activa su transmisión (PTT) la caja AS2x2 intercambia las salidas, pudiendo entonces la estación Inband salir por el Amplificador - lógicamente por la antena principal- y pasando la antena de recepción a la estación RUN. El conmutador AS2x2 puede ser gestionado por el Interlock 5R de forma que ya éste aplica las prioridades de cual de las 2 Radios (Run o InBand) tienen prioridad haciendo o no la conmutación de las antenas.

As an option to the Interlock we have just added the AuxBox

Any any equipment that don’t incloude an Inhibit signal can use this box for the microphone and cw interconexion.

So the Mic and CW connectors are conneted to this new box and from the box to your Radio. When the Inhibit is activated by the Interlock 5R, the signal will activate the relays inside the AuxBox so the radio will not transmit.
