4O3A RS3000 2x2 Reversible Coaxial Crossover RF Switches

4O3A RS3000 2x2 Reversible Coaxial Crossover RF Switches are high-power, 2x2 coaxial crossover switch designed to instantly swap antennas and amplifiers between two radios—ideal for SO2R, Multi-Single (MS), or Multi-Two (M/2) contest configurations. Switching is done when a DC voltage of 12 volts is applied, or with the push of a button, operators can dynamically reassign the best antenna and amplifier setup to the radio that needs it most—perfect for chasing multipliers or breaking pileups when the in-band station needs more firepower.

The RS3000 simplifies station automation by allowing seamless reconfiguration of RF paths without physically rewiring. It supports local control or remote switching via the optional RS3000 Controller (sold separately), which includes PTT interlock logic to prevent switching during transmission—ensuring safe and interference-free operation.

Key Features

• Instant RF Path Switching: Swap antennas and amplifiers between two radios with a single command—ideal for dynamic contesting environments.

• High-Power Handling: Engineered for full-power HF operation up tp 3kW, suitable for demanding SO2R and multi-op setups.

• Safe Switching Options: Manual or Automatic Remote switching via the optional RS3000 Controller (sold separately), which ensures switching only occurs when both radios are idle, preventing accidental RF collisions.

Additional Features and Specifications:

• Configuration: 2 radios/2 antennas/amplifiers (2x2 crossover)

• Control: Manual or remote (12VDC switching; RS3000 Controller recommended, sold separately)

• RF Connectors: UHF SO-239 female, or Type-N

• Use Cases:

  - SO2R - (Single Operator, two radios)

  - MS - (Multi-Single) Multiple operators, one transmitted signal

  - M/2 - (Multi-Two) Two transmitted signals on different bands at the same time, and other flexible antenna routing scenarios.
