The Sun is one of the strongest radio sources. Monitoring solar bursts requires precise antenna systems. This work presents the design and application of a Log Periodic Dipole Antenna (LPDA) for monitoring solar activity in the 45–870 MHz range. The LPDA was connected to a CALLISTO spectrometer and used to capture solar flares and Coronal Mass Ejections (CMEs). Analysis included signal-to-noise ratio (3.9 dB), y-factor calculations, and burst detection in the 228–240 MHz range. The LPDA setup proved effective for low-frequency solar monitoring with reliable bandwidth and gain estimates.
