The ALP690 is a high-performance LPDA (log periodic dipole array) antenna with a bypassable, built-in RF amplifier for use with wireless microphone receivers in location or studio production. The design delivers +4 dBd of passive gain in a directional pattern to extend operating range, and, when DC power is applied, the amplifier applies gain to overcome loss in long coaxial cable runs. By offering both active and passive operation modes, the ALP690 can be used as a receiver antenna (active or passive) and as a transmitter antenna (passive only).

  • Selectable RF filtering 470-608 MHz or 470-700 MHz
  • Directional pattern with 4 dBd RF gain
  • Built-in RF amplifier with adjustable gain for offsetting cable loss
  • Keypad and membrane switches with LED readout for quick setup
  • Automatically switches to passive mode when no DC power is present on the coaxial cable
  • Durable finish and weather tolerant construction for indoor/outdoor use
  • Skeletal structure reduces wind loading
  • Versatile mounting options with the supplied mount and optional mounting adapter kit
