    ANTENNA SWITCH 2x2

    The antenna Switch AS2x2 is a 2 Input Ports into 2 Outputs Ports, usefull for a contest station where you have a Main Radio (RUN) and a Multiplier Station (Inband) at the same band. In this way, the RUN station uses the main antenna(s) while the Inband station is looking for new multipliers or QSOs and uses an RX antenna located far from the main antenna. As soon as the Inband station passes to TX, the switch AS2x2 inverts the antennas, passing the Inband station to use the Main antenna while the RUN does not run out of antenna put to use the antenna of RX.

    The AS2x2 can be connected between the RUN Radio and the Linear Amplifier (in case a Amplifier is used) and between the Inband Radio and the RX antenna. As soon as the Inband Radio activates the PTT the AS2x2 will exchange the outputs, so the Inband will use the Linear Amplifier and the RX antenna will be assigned into the RUN Radio.

    The AS2x2 can be used combined with the Interlock 5R so in this case, the Interlock 5R will control automatically the antenna switching.

  • Interlock 5R

    The Interlock 5R device ensures the compliance with Radio Contest rules for the participation in Multi-Operator categories:

     

    • Multi/Single: Only one transmitted signal on one band permitted.
    • Multi/2: Maximum of two transmitted signals on two different bands may be used at any time.
    • InBand: Only one signal allowed between a Radio and its associated InBand.

     

    The Interlock supports 5 Radios (R1, R2, R3, R4 & R5) and it can be configured as M/S or M/2 so the unit will monitor that only one (M/S) or two (M/2) signals are on Air.

    In case of rules violation, the unit will activate an Inhibit signal that will be used by the Radio (Yaesu/Elecraft) to STOP the transmision of the signal to the antenna.

  • TRX-FEL

    The TRX-FEL (Transceiver Front End Limiter) is a RF protector and limiter for your radio transceiver. Installed between the antenna or amplifier and the transceiver, it requires to be connected the PTT signal from the radio. By default (reception) it will limited any RF signal and will avoid to damage the receiver in the proximity to other transmitters. When the PTT is activated by the radio, the Front End Limiter will be by-passed.

    This model is highly recommended in multi operator contesting, SO2R or Field Day. 

    Specifications in RX (FrontEnd activated)

    • Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.06:1 Range 1.8-29Mhz

    Specifications in TX or ByPass (FrontEnd disabled)

    • Insertion lost better than 0.04dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.05:1 Range 1.8-29Mhz
    • Max power 150W

  • RX-FEL

    The RX-FEL is a RF protector and limiter for your radio receiver or SDR. Installed between the RX antenna and the receiver, it will limited any RF signal and will avoid to damage the receiver because strong signals.

    The RX-FEL is a device that will protect the receiver front end from high level signals when operating in the proximity to other transmitters which could damage it. Situations such as multi op contesting, SO2R or Field Day. 

    • Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.06:1 (reception)
