The AKG APS4 is a wideband UHF active antenna and power splitter. It is designed to feed up to four wireless receivers with the RF signal. It can also supply power to all connected receivers via BNC cables.

The APS4 offers wideband UHF operation between 470 and 952 MHz. Thanks to the unit’s adjustable RF-level attenuation settings, you can be sure you’ll maintain your maximum operating distance, even if you’re employing different types or lengths of cable throughout your system.

On the rear of the device you’ll find two antenna inputs that supply 10 VDC for powering up to three active wireless-system elements per path. So, one RF path can power an active antenna and two antenna boosters. You’ll also find two sets of four BNC antenna output connections for feeding up to four diversity receivers as well as two antenna outputs for cascading up to three APS4s in total.

The unit takes up on a half-rack worth of space and ships with all the gear you need to install it into a rack. Also included are front-mount antenna cables and ten BNC cables to get you started. The power supply is not included, but it is available separately.
