Log Periodic Antennas 30 MHz - 6000 MHz Log Periodic Antennas are a solution for illumination of anechoic chambers and far-field antenna measurements. Antenna gain is a performance indicator gauged in comparison to a reference source. Verizon T-Mobile All Bands.
Log-Periodic antennas antennas are designed for the specific purpose of having a very wide bandwidth. The main advantage of this antenna is that it exhibits constant characteristics over a desired frequency range of operation. The construction and operation of a log-periodic antenna is similar to that of a Yagi-Uda antenna.
