Active log periodic antenna, 470-960MHz

  • Extends system range
  • Switchable 3 dB and 10 dB of active gain
  • Mounts on standard threaded microphone stand

The ALPA is an active directional antenna with switchable 3 dB and 10 dB of amplified gain, which increases the desired RF signal while rejecting unwanted RF signals. ALPA mounts on a standard threaded microphone stand for easy placement. Intended to extend system range, ALPA should be used in conjunction with high-quality, low-loss coax cables such as items from the Electro-Voice CXU grade cables, which are available in various lengths. RF gain at the antenna can be increased by placing an RE3- ACC-RFAMP RF booster in line using short coax.
