ACOM 2000SW | Remote Antenna Switch

ACOM 2000SW | Remote Antenna Switch


Usage
The ACOM 2000SW is a remote 1 out of I0 antennas switch designed for outdoor use (dust and rain protected). The 2000SW switch is controlled via 4-bit parallel BCD code input commands.

Compatibility

  • Directly compatible with ACOM 2000A automatic HF linear amplifier and ACOM 2000S antenna selector;
  • Control is compatible with other systems via 4-bit BCD code input commands;
  • For manual control, only a simple BCD-coding switch plus 27 VDC / 150 mA unregulated power supply are enough;

Integration capabilities

  • When used in combination with the ACOM 2000S antenna selector and the ACOM 2000A Automatic HF Linear Amplifier, antenna selection information generated by the ACOM 2000A is communicated to the 2000S. The 2000S displays the currently selected antenna and drives the control signals needed to operate the remotely-located ACOM 2000SW;
  • The 2000SW is controlled by 4-bit BCD code (positive or inverted, internally selectable) input commands. This make integration in other automatic antenna systems very easy;

Continuous carrier
Up to 5 kW continuous carrier: Teflon (PTFE) insulated connectors for 100% duty cycle (continuous) operation.

Construction
Gold-plated and bifurcated contacts for excellent reception, no contact-derived cross-modulation phenomenon. Flat coaxial line construction for excellent VSWR and crosstalk isolation.

Protection
Anti-hot switching self protection for reliable contact operation. Monitors RF incoming power and generates a "ready to transmit" output signal for maximum operating flexibility. Grounds unused antennas during operation for excellent crosstalk isolation. After switching off, all antennas are automatically grounded for maximum lightning safety.

Antenna switching time
Only 0.15 seconds operating time.

Easy to istall
Only 2 holes needed, mounting bracket included.
