AKG AB4000 EW UHF Antenna Booster

The AB4000 EW exists because coax loses signal, and a remote antenna that solves a coverage problem can create a level problem 60 m of cable later. One booster makes up 3.5 to 17.5 dB of cable attenuation across 470 to 952 MHz, and two can be cascaded when the run is genuinely long. Cable-length switches on the body set the amount rather than leaving it to guesswork, and an in-line LED shows it is powered.

It works with every AKG antenna, active or passive - RA4000 B/EW, RA4000 EW, SRA2 B/EW and SRA2 EW - and lives in a rugged waterproof metal housing so it can sit outdoors at the antenna end of the run. Input and output are both female BNC into 50 ohms.
