Lectrosonics ALP Series Shark Fin LPDA Antenna 450-862 MHz | Lightweight

The Lectrosonics ALP Series targets RF coordinators, production sound mixers, and system integrators who need reliable directional antenna coverage across wide frequency spans without locking into a narrow band. Built on a Log Periodic Dipole Array design, the ALP Series delivers a consistent directional pattern from 450 to 862 MHz with VSWR below 2:1, making it a practical choice for multi-channel wireless rigs and frequency-agile systems where narrow-band gain antennas would require compromise or substitution.

Constructed from 1/8" FR4 fiberglass circuit board material, these antennas are rugged enough for demanding field and touring environments. The mounting block accepts three common thread sizes, and the assembly can be repositioned between horizontal and vertical orientations by removing four screws, allowing placement away from reflective surfaces to preserve the natural LPDA pattern. Versions suited for indoor installation and field production are available across the family, providing a single platform antenna solution from fixed-installation broadcast environments to outdoor event wireless deployments.

For engineers running long coaxial cable runs or passive RF splitters, the ALP Series design philosophy addresses the gain-versus-noise tradeoff directly, with documented compatibility with Lectrosonics receivers, the UMC16B multicoupler, and the BIAS-T power inserter for phantom powering via coax. Optional thread adapters allow mounting on mic stands, lighting clamps, and photo or video tripods, keeping the ALP Series deployable across nearly any production rigging scenario.
