J.W. Miller Model 2104, 4 Section Air Variable Capacitor, 17-380 pF per section

Brand / Identification:
Miller (J.W. Miller), Model No. 2104. Marked “MILLER No. 2104 4 Section Variable Cond. 365 MMFD.”Specifications:
  • Sections: 4
  • Capacitance range: Approximately 17–380 pF per section (marked 365 mmfd / pF maximum)
  • Voltage rating: Approximately 1000 V peak (estimated from 1/64 inch plate spacing using standard air-gap charts; typical for this style of broadcast/multi-gang Miller unit; exact rating not marked)
  • Plate spacing / air gap: 1/64 inch
  • Shaft: 3/8 inch diameter
  • Overall length: 7 5/8 inches
  • Other dimensions: Width 3 3/8 inches, height 3 1/4 inches
  • Construction: 4-section (multi-gang) air variable with metal frame, ceramic or equivalent insulation between sections, common rotor shaft, and individual stator terminals
This is a classic multi-section Miller air variable capacitor suitable for multi-band receivers, transmitters, antenna tuners, or experimental RF projects. Sections can be used individually or paralleled for higher total capacitance.
