A radio spectro-polarimeter was developed at the Gauribidanur radioobservatory to study the characteristics of the polarized radio waves that areemitted by the impetuous solar corona in the 50 - 500 MHz frequency range. Theinstrument has three major components : a Cross-polarized Log-Periodic DipoleAntenna (CLPDA), an analog receiver, and a digital receiver (spectrumanalyzer). This article elaborates the design and developmental aspects of theCLPDA, its characteristics and briefs about the configurations of the analogand digital receivers, setting up of the spectro-polarimeter, stage-wise testsperformed to characterize it, etc. To demonstrate the instrumental capability,the estimation of the solar coronal magnetic field strength (B {\it Vs}heliocentric height), using the spectral data obtained with it, is exemplified.  Throughout the above band, the CLPDA has a gain, return loss and polarizationcross-talk of $\approx$ 6.6 dBi, $\lesssim$ -10 dB, and $\lesssim$ -27 dB,respectively. The design constraints, the procedure to tune its impedance andto minimize its dimension, etc. are elaborated. The analog receiver has a noisefigure of $\approx 3$ dB and a receiver-noise-temperature ($T_{rcvr}$) of about290 K. The receiver-flux-density ($S_{rcvr}$) is $\approx 5.3 \times 10^3 $,and $\approx 5.3 \times 10^5$ Jy at 50 and 500 MHz, respectively. The observedspectral data shows a Signal-to-Noise Ratio and Dynamic range of about 30 dBand 40 dB, respectively, at 50 MHz. The average polarization isolation /cross-talk of the CLPD varies from -30 dB to -24 dB over an azimuthal angle of$\pm 45^\circ$ with respect to the reference position angle ($0^\circ$). Theaverage degree of circular polarization (DCP) is $\approx 100\%$ at thereference position and found to decrease gradually and reaches $\approx 80\%$at an azimuthal angle of $\pm 45^\circ$.
