The AKG AB4000 EW is a professional antenna booster to compensate signal loss on long antenna cables. One AB4000 EW can compensate 3.5 to 17.5 dB of cable attenuation. Up to two boosters can be cascaded in case of very long cable runs.

The AB4000 EW comes in a rugged, waterproof metal housing and features an in-line power LED display and cable length adjustment switches. It works with all active and passive AKG antennas, RA4000 B/EW, RA4000 EW, SRA2 B/EW and SRA2 EW, and operates in a frequency range from 470MHz to 952MHz.
