You don't understand how brutal lightning is in most places. A Type F
grounding block costs a couple bucks; an 8 foot rod is $8; a clamp is a
couple bucks (I trust he can scrounge-up some #10 copper wire); why skimp?

If lightning is a problem then ground the coax but use a ground separate
from the antenna ground so noise currents from the radio plugged into
the mains has some isolation from the antenna circuit.

If the antenna ground is a wire on the ground under the aerial then the
coax could be attached to a ground rod.


The black terminal should connect to the grounded mast. Otherwise,
there are established procedures, as stated in the National Electrical Code.
