Lectrosonics AMJ Swiveling SMA Antenna For Wireless Belt Packs

The Lectrosonics AMJ is a direct replacement for the standard AMJ antenna, designed for professional wireless system operators working with UM series belt packs, newer SM series belt-pack units, and SR receivers. Its color-coded design simplifies frequency block identification on busy stages or in multi-channel wireless racks, reducing setup errors during fast turnarounds in live production and touring environments.

Construction centers on a steel wire rope body terminated with a stainless steel SMA connector, a combination chosen for field durability over the long-term abuse of daily load-in and load-out. Where standard antennas fail under repeated bending and contact with costumes or clothing, the wire rope build resists kinking and breakage. The standard male SMA connector fits the transmitter body without adapters, keeping the profile clean and the RF connection solid.

Buyers must specify a frequency block at the time of order, for example AMJ-24, to receive the correct tuned antenna for their system. For operations requiring multiple blocks or a user-selectable solution, Lectrosonics also offers the AMJKIT (Rev. A). This antenna is the practical choice for rental houses, touring engineers, and production companies maintaining large inventories of Lectrosonics wireless gear.
