Farley Antenna Coil RF-2-S is a legacy passive electronic component manufactured as a replacement part for antique radio receivers. Constructed on a square-profile form factor, this Radio Frequency (RF) coil provides coupling between external or internal antenna arrays and the front-end amplifier or detector stages within classic superheterodyne or TRF (Tuned Radio Frequency) receiver layouts. Featuring precision-wrapped wire windings designed for high efficiency (Q-factor), it provides the inductive impedance matching needed for accurate frequency tracking and image rejection across standard communication bands. The compact architecture uses structural solder lugs or wire leads for seamless implementation into vintage point-to-point electronic chassis.
