4O3A 8xAB Antenna Switches

4O3A 8xAB Antenna Switches integrate eight independent A/B switches into a single compact unit, enabling seamless switching between multiple antennas and radios. When paired with two 403A Antenna Genius switches (O3A-40-AG8X2 or O3A-40-AG8X2-N), it forms a powerful 8×4 antenna matrix, allowing up to eight antennas to be routed to four radios with exceptional isolation. Built with the needs of high-power stations in mind, the 8xAB Switch delivers robust performance, intuitive operation, and a clean, maintainable installation. The primary motivation behind the 8xAB switch is the integration of two Antenna Genius smart switches into an 8×4 Super Switch.

Key Features:

- A/B Switch Design: Combines eight A/B switches in one enclosure for streamlined station integration.

- High Isolation Matrix Capability: Forms an 8×4 antenna matrix with Antenna Genius switches, offering 56–70 dB isolation at 30 MHz.

- High Power Handling: Supports up to 3500W input power, making it ideal for high-power contesting environments.

Additional Super Switch Notes - See the note below, and the diagram in the image section above when creating a 8x4 Super Switch installation using 2 Antenna Genius switches.

• The Antenna Genius that’s connected to the OM module has the priority when selecting antennas.

• All unselected antennas are routed to R3 and R4 automatically.

• When R1 or R2 select a port, the output module will route the antenna through the AB switch.

• There is no special protection in place, meaning R1 and R2 can select any antenna at any time.
