Grounding unused inputs greatly increases
the isolation of the switch.

> Hello T-T'ers,

> at the schematic, all "unselected" antennas are grounded.
>
> I was wondering what the logic is behind the grounding
> of the antennas haven't been selected. Can someone
> shed some light on this for me? I was thinking about
> modifying the switch so that it does not ground any of
> the other 4 antennas that have not been selected.

> Thanks for any help on this!
