Product description CES 2019: Lectrosonics Announces the ALP690 Active UHF LPDA Antenna Read More rdarvsuwcyzyvqrxzbsybaaaayb The Lectrosonics ALP690 is a high-performance active/passive UHF LPDA (Log Periodic Dipole Array) antenna with a built-in RF amplifier to extend the operating range of wireless microphone receivers or base station transmitters in location or studio productions. The unit delivers +4 dBd of passive gain, while the built-in RF amplifier can be engaged to supply -6 to +12 dB of gain in adjustable 1-dB steps for overcoming signal loss in long coaxial cable runs.The antenna is powered via DC bias inserted on the coaxial cable connected to the 50-Ohm BNC jack. This power can be supplied by a Venue Series receiver, an active multicoupler, or an inline BIAS-T device. The unit automatically switches to passive mode when no DC power is present on the coaxial cable, allowing you to use it not only for receivers but for IFB or IEM transmission applications as well.A membrane switch keypad and LED readout on the control panel allow for quickly adjusting RF amplifier gain, filter bandwidth, and display brightness—convenient when working in low-light environments. As an active antenna, the ALP690 operates with a broad bandwidth to accommodate multi-channel systems. The filter bandwidth is adjustable from 470 MHz at the lower end to either 608 or 700 MHz at the top end for use in the US market or abroad. The skeletal frame reduces wind load and is constructed with copper traces on a .133" thick glass epoxy high-pressure thermoset plastic laminate material with a durable finish. The ALP690 can be mounted horizontally or vertically with the supplied mount or an optional mounting adapter kit (sold separately). - Features and Functions
