4O3A Antenna Genius 8X2 Smart Antenna Switches

4O3A Antenna Genius 8X2 Smart Antenna Switches are high-performance, LAN-enabled antenna switches that connect eight antennas to two radios—ideal for SO2R (Single Operator, Two Radio) and multi-operator contesting. Designed for seamless integration with FlexRadio systems and third-party radios, they support automatic or manual antenna switching via LAN, BCD, or the downloadable Windows control app. Built with a rugged stainless steel chassis and advanced hardware-level interlocks, the AG8X2 ensures that no two radios can transmit on the same antenna simultaneously, protecting your equipment. With exceptional port-to-port isolation and support for up to 3000W, the Antenna Genius 8X2 delivers reliable, high-isolation switching for demanding HF and 6m operations.

Key Features

- True SO2R Support: Capable of connecting 8 antennas to 2 radios with 70–90 dB isolation and built-in interlocks to prevent cross-transmission.

- Smart Control Options: Supports LAN/WAN control, FlexRadio integration, BCD, and manual switching via Windows app or Pin-to-Port.

- High Power & Isolation: Capable of 3000W @ 1.5:1 SWR CCS (e.g. RTTY) duty cycle for five minutes, with industry-leading port isolation—up to 90dB at 14MHz.
