Abstract: Radio transient signals from the Fast transient sources vary their brightness across the spectrum and in time. Several arrays across the globe search for FRB-like transients, typically between 500 and 800 MHz. It will be interesting to study these signals below 500 MHz. As we have the BURSTT telescope out-trigger station in the observatory, we are considering developing a lower frequency follow-up study instrument at the Gauribidanur observatory. The antennas will be configured to form a circular array with non-redundant baselines in a circle of radius about 100 meters. A sophisticated receiver system consisting of Low Noise Amplifiers and RF front end receivers to transmit the signals over optical fiber path are developed. This paper describes the details of a new antenna and instrumentation designed to detect radio transients at low frequencies between 150 MHz and 700 MHz. It will also present the initial test results from observing transient sources (Solar and Pulsars) at the Gauribidanur Observatory.
