Lectrosonics ALP500 - LPDA Fin AntennaStandard remote antenna ideal for fixed applications. The ALP Series antennas are a Log Periodic Dipole Array (LPDA) design that provides a useful directional pattern over a broad frequency bandwidth. Many "gain antennas" (those designs with a directional pattern) are limited in bandwidth, making them awkward for use in multi channel wireless systems and with frequency agile wireless systems. With VSWR below 2: 1 from 450 to 862 MHz, the broad
