Lectrosonics ALP620 LPDA Skeletal Shark Fin Antenna for Fixed Application, 450-850MHz

The ALP Series antennas are a Log Periodic Dipole Array (LPDA) design that provides a useful directional pattern over a broad frequency bandwidth. Most "gain antennas" (those designs with a directional pattern) are limited in bandwidth. This makes them awkward for use in multi-channel wireless systems and with frequency agile wireless systems.

With VSWR below 2:1 from 450 to 850 MHz, the broad bandwidth of the ALP Series covers the entire UHF band used for Lectrosonics wireless microphone and IFB systems, yet still provides theh directional pattern needed to cover long distances.

All ALP Series antennas are constructed of 1/8" FR4 fiberglass board and are extremely rugged. The ALP620 is best suited for portable applications including temporary setups for field shoots. Additionally, the perforated design of the ALP620 makes it highly resistant to wind loading. None of the antennas in the ALP Series are intended to be left outdoors indefinitely. A sturdy aluminum housing protects the 50 ohm BNC connector.
