This paper describes how shrubs have been used as transmitting and receiving RF antennas. The variations of transmitting and receiving characteristics with moist and dry conditions have been studied extensively. It has been found out that the two sets of observations differ by 5–7dB. Modulated wave transmissions and receptions have been studied as well. The behaviour of such antennas are found similar to capacitive loaded T dipole antennas as the Antenna Factor in both the cases are comparable by around 10 dB. Finally it is found that mobile phone receptions are possible with a good performance.
