Select an antenna for Port A or Port B¶

Use the Antenna Genius applet to assign a specific antenna to Port A or Port B on your 4O3A Antenna Genius switch. This lets you control which physical antenna each radio port uses without leaving AetherSDR.

Before you start¶

The Antenna Genius applet must be visible. It is hidden until a device is connected or discovered. See Auto-discover an Antenna Genius on the LAN or Manually connect to an AG over a remote network.
The status label must read Connected — \<name> v\<version> before antenna buttons appear.
Open the applet by clicking the AG tray button on the right sidebar.

Steps¶

Click the AG tray button to open the Antenna Genius applet.
Confirm the status label reads Connected — followed by the device name and version.
Under the Port A heading, locate the antenna buttons populated from the device's antenna list.
Click the button for the antenna you want to assign to Port A. The button highlights to show it is selected.
To deselect the current antenna on Port A, click the same button again. The port returns to no antenna selected (antenna 0).
If your device has two radio ports, the Port B section is visible below the separator. Repeat steps 3–5 under the Port B heading to assign an antenna to Port B.

What each control does¶

Control	Behavior	Notes
Port A antenna buttons	Click to select an antenna on Port A; click again to deselect.	Blue = TX and RX permitted on the current band. Amber = RX only. Dim = no permission on the current band. Disabled if the antenna is already selected on Port B.
Port A band	Displays the active band on Port A, derived from the radio frequency.	Shows — when no band is identified.
Port A antenna	Displays the currently selected antenna name for Port A.	Shows \<ant> TX:\<alt> when TX is routed to an alternate antenna, and \<ant> [INHIBIT] when transmit is inhibited. Turns red during TX, orange on alternate TX or inhibit.
Port A AUTO	Toggle. Enables band-follow on Port A so the switch tracks radio band changes automatically.	See Enable AUTO mode so the AG follows radio band changes.
Port B antenna buttons	Click to select an antenna on Port B; click again to deselect.	Same antenna list as Port A. Hidden if the device reports only one radio port.
Port B band	Displays the active band on Port B.	Shows — when no band is identified.
Port B antenna	Displays the currently selected antenna name for Port B.	Same state display as Port A antenna.
Port B AUTO	Toggle. Enables band-follow on Port B.	Hidden when Port B section is hidden.

Tips¶

An antenna already selected on one port is disabled and dimmed on the other port's button grid. You cannot assign the same antenna to both ports simultaneously.
Amber-highlighted antenna buttons are available for receive but will not carry TX on the current band. Switch to a blue button before transmitting.

Troubleshooting¶

Port B section is not visible — The connected device reports only one radio port. Port B is hidden automatically in this case and is not available.
Antenna buttons are not shown — The device is not yet connected, or the antenna list has not loaded. Confirm the status label reads Connected — and wait a moment for the list to populate.
Clicking an antenna button has no effect — The button may be disabled because that antenna is already selected on the other port. Choose a different antenna or deselect it on the other port first.
A ShackSwitch device is discovered but does not appear in the Antenna Genius applet — ShackSwitch devices are excluded from auto-connection in the Antenna Genius applet and are handled by the ShackSwitch applet instead. Open the ShackSwitch applet to connect to that device.
