Could mast-mounted radar keep the Grand Fleet in contact?

Would radar mounted on the Grand Fleet's tallest masts have detected the High Seas Fleet at Jutland?

The fleets are judged close enough; tracking Beatty's force is another proposed advantage.

The follow-up concerns the Grand Fleet rather than the battlecruiser force. It imagines radar mounted on the ships with the tallest masts. The range is judged adequate even with a basic display. Knowing where Beatty's force is would provide another benefit; disappearing British contacts then become the subject of a joke about battlecruiser losses.
