WebLong Wire and Traveling Wave Antennas 13-1 The power gain and directive characteristics of the harmonic wires (which are “long” in terms of wavelength) described in Chapter 2 make them useful for long-distance transmission and recep-tion on the higher frequencies. In addition, long wires can be combined to form antennas of WebNon-Resonant Antennas. Non-resonant antennas or traveling wave antennas are configurations of antennas whose voltage and current can be represented as one or two traveling waves moving in the same direction. Non-resonant antennas exhibit a non-periodic nature. There is always a progressive phase pattern associated with the voltage and … parenting skills goals and objectives
