Oscillations of a skin depth with magnetic field were measured in single crystals SmAgSb$_{2}$ by using radio-frequency resonant technique. Comparison with directly measured de Haas -- van Alphen and Shubnikov -- de Haas oscillations revealed additional details in the frequency spectra, probably due to high sensitivity of the measurements $\Delta \rho_{min} \approx 20\;{\rm{p}}\Omega \cdot {\rm{cm}} $. The temperature evolution of the frequency spectra was obtained. The correlation of the observed oscillations with calculated Fermi surface and possible influence of antiferromagnetic ordering are discussed.
