I think we discussed this before, but I just caught myself again building antennas for the wrong frequency.
The SDS Hobby modules use a "positive logic" (I don't know what the exact english term is) when describing 1 or 0. 1 means a voltage is at the pin, which means no jumper or connection. 0 means no voltage, thus pin is shortened to ground.
Looking at their channel mapping:
This translates to 5945MHz having no connection at all or all dip switches being open.
Please be aware of this when sourcing your antennas.
Best ...
