In all the antenna books I have read there are copious diagrams of voltage

none of them has explained where the two points are that the voltage is
being measured between. Can anyone enlighten me on this please?

:-) You need a virtual ground to obtain those voltages. Actually,
they are deduced to exist because P=ExH and we can measure the
antenna current associated with a certain power level. Some purists
say that if a voltage cannot be measured, it doesn't exist. Some
detectives deduce its existence based on the laws of physics.
