The earthing stake was often used with both radio & wire communications. It can be seen in use with field phones & the switchboard. Earthing one side allows for single wire communications to be run between phones and this makes for both a quicker connection, and no confusion over which wire is earth etc. It does however provide a security problem in that anyone with a phone can easily tap into the wire & simply earth the other side. There is no risk of accidentally earthing the "live" wire & cutting communications thus alerting the enemy to the intercept.
