• Model: Hetorus Coil - Branston, Chas. A.; Buffalo,

• Notes
• Advertising:
  It does three things: Increases selectivity for precise tuning. Improves tone and volume of distant stations. Reduces static and interference to a minimum. Because: The Hetorus Coil has no pick-up quality of its own and amplifies only the signals to which the antenna is tuned. Being "fieldless" there can be no interaction either between the coils themselves or adjacent apparatus. They can therefore be mounted in any position or angle.
