On one of the Icom websites they have a 7 page PDF document specifically
addressing antenna grounding and they show the radio chassis grounded to the
"boat ground" (same as tuner) via copper foil. They don't explain the
reason but I believe they say it is important for performance.

I have an icom M700 with an AT-120 antenna tuner.
I understand the importance of good grounding for the AT-120, but do I
need to be as paranoid about grounding the M700 itself ?

Thanks
