For more information, review Andrew Corporation's installation for KOKH-TV Oklahoma City, Oklahoma. The custom pattern of the antenna was specifically designed to provide the best possible TV signal coverage in the Oklahoma City market. Andrew engineers created a balance between traditional requirements that typically call for transmitting the signal as far as possible and efficiently providing maximum signal to the viewing audience regardless of how near or far from the antenna they might be. A. Center fed antennas' main strength is long-range VHF coverage. Center fed antennas are also candidates when antenna maintenance and optimal null fill are not important.
End fed antennas are advanced technology.
They require more precision in design, but are more flexible, efficient, and effective performers. End fed antennas allow for more flexible pattern design and radiate energy more effectively. A center fed antenna radiates energy symmetrically, which means that a significant portion of the energy goes out into space. A. Center fed antennas inherently suffer from beam shift. Beam shift is not a problem with end fed antennas because of their asymmetrical design.
