Da montare preferibilmente ad una altezza di 3-6 mt dal suolo.
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 SWR below 2:1 from 470 to 700 MHz, the broad bandwidth of the ALP Series covers the entire UHF band used for Lectrosonics wireless microphone and IFB systems, yet still provides the 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 and ALP650 antennas are best suited for portable applications including temporary setups for field shoots, while the more economical ALP500 is well-suited for more permanent indoor installation. 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 on the ALP620 and ALP650 models.
An optional adapter kit is available for all three models that provides a variety of mounting options with the mounting block. The antennas can be mounted on horizontal or vertical surfaces by removing four screws and repositioning the mounting block. This helps to optimize the mounting away from nearby surfaces to reduce the effect of reflections and preserve more of the natural pattern of the antenna design.
