Would it be wise,

REPLY:
I wold not do it. The only ground you need it the safety ground provided
by the third wire on your AC plug.
Adding a separate ground wire does two things, both of which are bad:
1. It provides an additional path for lightning strikes which hit
nearby power lines, travel through your house AC wiring, through your
rig and into ground. Don't try to ground lightning via your rig. Keep it
away in the first place.
2. It provides a path for your transmitted RF to flow into the earth.
Dirt is lossy at RF. Keep your RF up ion the air where it belongs. If
you have RF on the chassis of your rig, you don't have a grounding
problem, you have an antenna problem, most likely unbalance in the feed
line, which can be cured by a choke balun in the feedline.
