Lectrosonics ALP690 LPDA Antenna with Built-In RF Amplifier, 470-692 MHz

Revolutionary RF Technology for Flawless Audio
The Lectrosonics ALP690 is a state-of-the-art LPDA (log periodic dipole array) antenna, designed to significantly enhance the reception and transmission capabilities of wireless microphone systems in both location and studio settings. With a unique ability to operate in both active and passive modes, this antenna provides +4 dBd of passive gain in a directional pattern, extending the operational range effortlessly. Whether you are powering it for active gain or using it in its passive state, the ALP690 adapts seamlessly to meet the needs of professional audio setups.

Dual-Band RF Filtering for Versatile Application
Equipped with selectable RF filtering, the ALP690 can operate within two distinct frequency bands, either 470-608 MHz or 470-700 MHz, making it versatile for use in different geographical regions. This flexibility ensures that users can optimize their systems for specific frequency requirements, enhancing the antenna's utility across various production environments.

Built-in Amplifier to Combat Cable Loss
One of the standout features of the ALP690 is its built-in RF amplifier with adjustable gain, which is crucial for overcoming the signal loss associated with long coaxial cable runs. This feature ensures that signal integrity is maintained regardless of distance, providing clear and uninterrupted audio quality, which is vital for professional broadcasts and recordings.

Effortless Setup and Operation
This antenna is not only high performing but also user-friendly, featuring a keypad and membrane switches with an LED readout for quick and straightforward setup. The automatic switch to passive mode when no DC power is available on the coaxial cable ensures continuous operation without manual intervention, enhancing both reliability and ease of use.

Robust and Weather-Resilient Design
Designed with durability in mind, the ALP690 boasts a weather-tolerant construction suitable for both indoor and outdoor use. The skeletal structure minimizes wind loading, which is particularly beneficial in outdoor environments, ensuring stable operation even in adverse weather conditions. The copper traces on a .133” thick glass epoxy high-pressure thermoset plastic laminate material ensure longevity and resilience.
