The article offers a look at some of the factors inhibiting the performance of radio frequency (RF) and transmission systems. The transmission of radio frequency via omnidirectional antennas is influenced by various factors including the size of the tower legs, the size of the tower face, the distance of the antenna from the tower, and the free space radiation pattern of the antenna. Tests and equipment used in measuring radio systems are discussed.
