470-960MHz Active Log Periodic Antenna

The ALPA is an active directional antenna with switchable 3dB and 10dB 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.
