This will likely sound silly but can someone explain to this ham why 2 meter mobile radios don't usually have a ground connection? (for RF grd)Am using it for base station.

1. It doesn't need one to operate.
2. It doesn't need one to be "safe".

Most people don't ground their TV sets, clocks, fans or most anything else in their homes that operate at much higher voltages than a transceiver.

Now, if you want to talk about the antenna, that'd be a different story.

Even HF **radios** don't require an RF ground. The antenna may, depending on its design, require one in the way of radials or a counterpoise. A balanced antenna like a dipole or Yagi or an antenna that includes it own counterpoise like a ground plane doesn't require an RF ground. Running a 15-20 foot piece of wire from the radio case to a 6-foot ground rod doesn't provide a credible RF ground anyway.

Now lightning protection grounds on the antenna and feed line entrance is a totally different story, not related at all to RF grounding.
