Lectrosonics ALP600 - Manual

TECHNICAL DATA ALP600
LPDA Antenna
The ALP600 antenna is a Log Periodic Dipole Array
(LPDA) design that provides a useful directional pattern
over a broad frequency bandwidth. Most “gain anten­
nas” (those designs with a directional pattern) are limited
in bandwidth. This makes them awkward for use in
multi-channel wireless systems and with frequency ag­
ile wireless systems.
The broad bandwidth of the ALP600 covers the entire
UHF band used for Lectrosonics wireless microphone
and IFB systems, yet still provides the directional pat­
tern needed to cover long distances.
The ALP600 antenna is constructed of 1/8” FR4 fiber­
glass board and is extremely rugged. This antenna is
best suited for portable applications including tempo­
rary setups for field shoots. It is not intended to be left
outdoors permanently.
A sturdy aluminum housing protects the 50 ohm BNC
connector. There is also an optional adapter kit that
provides a variety of mounting options.
The ALP600 can be mounted on horizontal or vertical
surfaces by removing four screws and repositioning the
mounting block. Orientation of the threaded adapter in
any other position than what is shown here may inter­
fere with the normal operation of the antenna.
Also it is important to locate the antenna at least a foot
or two away from nearby surfaces. Reflections from
nearby surfaces can alter the pattern and/or affect the
sensitivity of the antenna to certain frequencies.
