Nimon Positronic Transmitter Antennae

The pair of horn-like antennae protrude from the device’s casing as dedicated energy conduits. Their sleek metallic surfaces gleam under the laboratory’s harsh lighting, designed to channel the destructive power of the positronic circuit. As the Doctor and Romana examine them, the antennae emit a faint hum, their resonance mapping to the shifting walls of the lair. K9’s sensors detect an unstable energy signature, confirming their role in transmitting hymetusite-sourced destructive force.

S17E19 · The Horns of Nimon Part 3
Doctor and Romana uncover Nimon weapon secrets

The transmitter’s curved horn-like antennae operate as energy conduits, channeling the destructive hymetusite energy from the nuclear furnace. Their resonance is noted as the cause of the shifting walls in the laboratory, revealing their dual role as both structural disrupters and weapons components. Romana and the Doctor recognize their vulnerability to harmonic interference.

Before: Fitted to the transmitter device, emitting faint hums detectable by sensors.
After: Still active and resonant, becoming a focal point for the team’s plan to destabilize the Nimon’s system.

S17E19 · The Horns of Nimon Part 3
Doctor summons K9 to analyze Nimon device

The horn-like antennae of the transmitter function as dedicated energy conduction channels, their faint hum mapping to the shifting walls of the laboratory. They channel the unstable energy from the hymetusite crystals, transforming raw power into directed transmission capability. Romana identifies them as critical to understanding the circuit’s operational feedback loops.

Before: Protruding from the transmitter casing as static components of alien design
After: Fully integrated into the circuit’s feedback resonance, pulsing in time with the positronic machine’s unstable operations
