Dalek City Antennae

Towering antennae rise from the Dalek city's walls, connected by a key cable that channels static electricity through Skaro's irradiated atmosphere. The Doctor traces this line during sabotage, short-circuiting it with Susan's ship key to black out control room monitors and flicker city power. Alydon eyes them warily as the Doctor warns of Dalek beams that could paralyze or kill Thals flashing lights to signal. Daleks surround the saboteurs moments after, their ambush exploiting the duo's delay near the exposed system.
