The uranium-gold diantimonide UAuSb_2 belongs to a numerous family of ternary compounds crystallizing in a tetragonal structure of the HfCuSi_2-type (space group P4/nmm). In this paper the results of magnetization, electrical resistivity and thermopower measured along the main crystallographic directions are reported. Two magnetic transitions, a ferromagnetic one at T_C =31 K and probably an antiferromagnetic one at T_N = 43 K were found. The spontaneous magnetization at 1.9 K amounts about 0.8 μ_B for B ⃦c-axis. Electrical resistivity for j⊥ c-axis exhibits a T^2 exp(-Δ/kT) dependence at low temperatures and a Kondo effect at higher temperatures above T_N. The thermopower S for both main crystallographic directions shows a maximum at the temperature close to T_C and the lack of any anomaly at T_N.
