ali probleme mi pravi ova promjenjiva zavojnica.
nema nikakvih podataka za nju.

L1 - 3.5 Turns Variable Coil
3.5 Turns High Precision Variable Coil (65 - 79nH)

These tunable RF coils are ideal for precise frequency tuning of your FM transmitter / FM Receiver throughout the entire FM band (88 - 108MHz). The magnet wire is halfway embedded within the plastic providing excellent frequency stability. Variable coils may be used as a substitution for an air coil and a variable capacitor. Dimensions are 7mm x 10mm.
