I think your shed and radio gear should be wired up to "code".
What you do for an RF earth is another matter (what Doug suggests in his para 3 is good) and as the eleco indicated, regularoty-wise the RF earth should probably not be connected to the premises earth.
FWIW the plumbing here is all buried copper pipe, and the switchboard earth goes to an earth stake which itself is connected to the pipe system underground. When setting up my station, initially I had my RF earth connected to a copper pipe that came up out of the ground and into the house via a hole in the brickwork, on the corner where my radio room is.
50Hz hum resulted, so I put in a separate RF earth system along the lines that Doug has suggested.
