Pagination or Media Count:
A HEMAC Hybrid Electromagnetic Antenna Coupler is used to couple r- f energy in the medium frequency range 400-425 kHz to an oak tree that is used as an antenna. A discussion of the measured impedance data and the effects of the nearby terrain are presented along with the conclusions reached.
