Wildlife tracking technology is a method routinely used in the detection of small animals or big animals. Normally, a radio tracking using a low frequency between 30MHz to 300MHz known as Very High Frequency (VHF). In this study, a band of Ultra High Frequency (UHF) with a frequency 315MHz is used as a transmitter. While a encoder HT12E is used as a function of generate a data signal to the RF Transmitter module 315MHz to transmit. The signal sent by the transmitter detected by Yagi antenna as a receiver and was designed at a frequency of 315MHz with a gain is 10.68dBi. Received power detected by Yagi antenna shown at Anritsu Spectrum Analyzer. The highest differences between power received at vegetation area compared to open area is about 10dBm while the furthest distance of the receiver can be traced in the vegetation area is about 67 meters, and for open area is more than 70 meters. The results of this study agreed with Tamir’model for propagation in forest whereas can be used in a prediction of initial pattern of power received signal which is gradually decrease if a receiver moves away from the transmitter over much larger distances.
