[Antennas] Tuner Ant Input Grounding

[Jerry]

Please reply off list to   n6vg at lanset.com

I am looking for an antenna tuner/matcher that has at
least 3 coax input and that grounds the unselected input.
If there is a position that grounds all inputs when not in use
that would be a plus.  Power handling capabilty  not an issue.

Does such an animal exist?

Thanks and take care from Jerry N6VG in Sacramento, CA.
