A second test with a fourteen-metre antenna on 18 August 1917 established that contact could be made with an aircraft within a distance of two kilometres provided that the tank was not moving, and it was decided to equip the command tanks of two units, AS 11 and AS 12, with an Émitteur 10ter radio set.
Po druhom teste so 14-metrovou anténou 18. augusta 1917, kde sa otestovala možnosť kontaktu s lietadlom vzdialeným 2 km, (za predpokladu, že tank stál) rozhodlo sa o vybavení veliteľských tankov dvoch jednotiek, AS 11 a AS 12, rádiovým setom Émitteur 10.
