The PLPA is a passive directional antenna, which increases the desired RF signal while rejecting unwanted RF signals. PLPA mounts on a standard threaded microphone stand for easy placement.

Intended to extend system range, PLPA should beused 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 further increased by placing an RE3-ACC-RFAMP RF booster in line using short coax.
