Activelog periodic antenna,470-960MHz.

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 coaxcables 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.
