You get one, Mica Ceramic Compression Variable Capacitor 7-100pF RF Power Trimmer Tested. See pictures.

For Measurments please see pictures,  

These are great for use in RF power amplifier tuning & impedance matching circuits, antenna tuners, oscillators & tuned circuits such as notch, band pass, & harmonic filters, having such a wide variable capacitance allows them to be used in many RF applications from HF VHF & UHF frequency ranges.

These exhibit excellent temperature stability & KW rating RF power handling with using both brass conductors & ceramic substrate.
