You will be measuring a whole load of other carp, such as the line conductor all the way back to the transformer, some transformer winding resistance, the transformer earth mesh/rod/whatever AND the lightning conductor. How do you know what resistances are attributable to each part.

You don't need to drive 4' long test electrodes into the car park to get valid readings from a pukka earth resistance tester...

This particular installation is a Church surrounded by a tarmacked car park.
Also, to prevent theft of he copper rod, the electrode is contained in a steel tube to a height of approximately 4M.

Tarmac does not prevent a proper test being carried out. Surface contact electrodes can be used for the test connections, small piles of damp chain are often mentioned as a possible option
