Lectrosonics ALP500 Log Periodic Directional Antenna

Built for fixed indoor installations, the Lectrosonics ALP500 is a log periodic antenna that gives wireless receivers a directional pickup pattern across 450 to 862 MHz.

Its log periodic dipole array (LPDA) design keeps a directional pattern over a wide bandwidth. Unlike many narrowband gain antennas, it suits multi-channel and frequency-agile wireless systems. It adds 4 dBd of gain over a dipole for longer reach.

The body is 1/8 in FR4 fiberglass circuit board, and the connector is a 50 ohm BNC. The mounting block takes 1/4-20 and 3/8-16 tripod threads and 5/8-27 mic stand threads. Four screws let the block move for vertical or horizontal mounting. Mount it vertically, in the same plane as the transmitter antennas, and away from reflective surfaces.
