    Low Resistance - Low Distributed Capacity.
    Wires are space wound, adjacent coils are parallel, air insulated and so separated that while capacity is reduced to a minimum, inductance is maintained at a high point of efficiency.
    Greater Tuning Range - Greater Selectivity.
    These coils are very uniform, both in inductance and distributed capacity, so that if desired they may be geared for single control of the three tuned stages. A minimum amount of material is used in the field of the coil, and an anti-capacity cement is used only where the wires cross. Coils are coupled so as to reduce capacity coupling to a minimum. Green double silk covering provides high insulation and gives a fine appearance to the coil.
