Reactone Tension Wound Low Loss Coils

Reactone Tension Wound Low Loss Coils

Reactone Coils are tension-wound because that gives them greater rigidity, complete uniformity, and their structure (better for coupling). They are the only correctly tension-wound, former-less Coils.
Reactone Inductance Coils are wound on patented machines that apply a constant tension to the wire throughout the winding-the same at the periphery as at the beginning: the machines automatically compensate for the greater speed at the periphery and thus avoid stretching of the wire and consequent lack of uniformity. Uniformity means definite calibration; you can depend on each Reactone Coil tuning to the wavelength specified. With tension winding we are able to dispense with all ebonite, empire tape, or other substances that introduce additional self-capacity; and at the same time secure a 'unique low-capacity formation that makes tuning sharper, signals stronger, and reaction readier.
