Sennheiser AWM 4 SpeechLine Wall-Mount Antenna

The AWM 4 is the four-element version of Sennheiser's SpeechLine remote antenna, tuned to the 1.9 GHz band the system runs on and housed in a rugged metal bar rather than plastic. Four antennas mean four diversity paths, which is what a larger room or a multi-receiver rack wants once two stop being enough.

Mounting is the same as its two-element sibling: two 9 mm holes on the back for a wall, or a 3/8 inch internal thread on the bottom for a stand. R-SMA bulkhead jacks sit on the underside so the cable run leaves cleanly. Feed several SL rack receivers from it through the SL PASC passive splitter.
