ALP650 - active LPDA antenna

ALP650 – UHF Shark Antenna, Active

The antennas of the ALP series are based on the proven Log Periodic Dipole Array (LPDA) design and offer an effective directional reception pattern across a wide frequency range.

This model features a built-in amplifier, specifically designed for long cable runs. Power is conveniently supplied via phantom power from a Venue receiver, UMC16, or Bias T. The skeletal construction reduces wind load – making it ideal for outdoor installations or mobile setups.
