AntennaJet ASM300 - Active Antenna Switch and Mixer
PC-Controlled 3-Way Antenna Switch & Mixer
With the AntennaJet ASM 300, we add another component to our supplies of receiving equipment. It is USB-controlled and you can connect up to three different receiving antennas from 9 kHz - 300 MHz loss-free to one output socket.
Additionally, you can combine all three input channels according to your needs. They are then connected in phase to the output socket. Thus you can always find the best combination of antennas when receiving conditions are bad.
Because there are no mechanical components like relays, the switching of the channels is done electronically by using active elements. So above average intermodulation values (IP3:+40 dBm at 7MHz typical) and extremely high insulation values are achieved. The electronics are installed in strong aluminum profile housing.
The HF-inputs are BNC and are protected against short and pulse-shaped voltage surges with complex ESD protection circuits. Because the voltage supply is integrated via USB, you do not need an additional power supply, which make the ASM300 ideal for portable operation.
