Abstract :
The paper describes short range VHF-UHF radio propagation measurements performed in a forested environment using low TX/RX antenna elevations. An empirical path loss model is proposed having as parameters the frequency, antenna heights and forest geometry. Furthermore the short term fading dynamics are also presented
