On the HamRadioHelpGroup someone asked:
I’m in a second floor apartment right now and thus do not have access to an efficient grounding possibility….Does a 100 what radio represent a significant hazard if not grounded properly?
To which, Mark, K5LXP, replied:
Yes. If it fell on the ground improperly it would break. Grounds are for AC shock protection. The rig operates on 12V. No shock hazard there.

Although if your antenna system isn’t balanced you might get a bit of a tingle from stray RF. I got a surprising zap once when I accidentally keyed a 5 watt CB with no antenna attached.
