Why an electronic-warfare ship is useless in the Napoleonic Wars

Electronic warfare only becomes useful once an opponent depends on radio emissions, making the Russo-Japanese War an early edge case and the world wars much better fits.

Question

How much could a modern electronic-warfare ship change the Napoleonic Wars?

Short answer

Almost nothing, because there are no radio communications to attack; the capability only begins to matter around the Russo-Japanese War and First World War.

Notes

A modern electronic-warfare ship sent to the Napoleonic Wars would find no radio network to intercept, jam, or exploit. Its specialized mission therefore contributes almost nothing to the communications system of that era. The Russo-Japanese War is the earliest plausible setting in which the capability starts to matter. The First World War offers a much stronger target environment, while the dense electronic systems of the Second World War would finally let the ship use its role fully.
