AUDAC ASK40S 4-Way Antenna Splitter Kit

One aerial, four tuners. The ASK40S divides an incoming antenna signal four ways so a rack of radio tuners can share a single roof feed instead of each needing its own run. Its 5 to 2300 MHz pass band covers FM and DAB / DAB+ alike, so the same splitter serves an analogue and a digital install.

It ships as a complete kit rather than a bare splitter: four F/F coaxial output leads, two at 0.4 m and two at 0.6 m, plus a twist-on F-type input connection. That is everything needed to land it in a rack next to the tuners it feeds.
