The detector element is actually mounted in vertical position on the front panel. The antenna circuit can be tuned to wavelengths shorter than the resonant wavelength of the antenna by using the series variable capacitor. Inductance of the primary winding is changed through use of two multi-point switches. Coupling between primary and secondary windings is varied with a rack and pinion adjustment.
