Recommendations on antenna mounting

minating resistor (50 Ω) to minimize interfering signals and
maximize transmission power.
Signal loss due to extension cables and antenna
splitters
In this scenario, the use of extension cables and antenna split-
ters with a remotely mounted antenna may result in loss of
transmission power, depending on the cable length.
You can compensate this signal loss by configuring the trans-
mission power of the receiver accordingly. Observe the follow-
ing minimum transmission power settings (SL Rack Receiver
DW: System Settings menu -> RF Power) for the respective
cable lengths. The antenna splitter causes about as much sig-
nal loss as a cable length of 15 m. These losses must be includ-
ed in the calculation of the transmission power level.
We recommend the following cable lengths in combination
with the antenna splitter:
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 1 m
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 5 m
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 10 m
• Receiver to splitter: 5 m -> splitter to AWM 2/4: 1 m
• Receiver to splitter: 5 m -> splitter to AWM 2/4: 5 m
• Receiver to splitter: 10 m -> splitter to AWM 2/4: 1 m
Cables longer than 10 m are not recommended for this
variant.
This results in the following transmission power levels to be
set in the menu of the receiver or simultaneously for all receiv-
ers in the Sennheiser Control Cockpit software:
• 5 m cable length plus splitter -> at least level 2
• 10 m cable length plus splitter -> at least level 3
Direct line of sight
▷ If possible, position the antennas so that there is a direct
line of sight (without obstacles) between the transmitters
and the antennas.
