LINK A TO PS, LINK B TO PS: These two BNC outputs carry the RF signal of the two antennas A and
B. You can connect the LINK outputs to the antenna inputs of another PS 4000 antenna splitter to
daisy-chain several antenna splitters.
Note that you will need one optional PSU 4000 central power supply each to power three PS 4000
antenna splitters.
The PSU 4000 central power supply delivers a 12 VDC, 2 A secondary voltage for powering three
PS 4000 antenna splitters and the receivers (12 max.) connected to the antenna splitters. For details refer
to the PSU 4000 user manual.
One passive directional antenna, one active directional antenna, and one active omnidirectional antenna
are available for the PS 4000 antenna system. All antennas are wideband devices for the entire
WMS 4000 UHF band.
The active antennas are powered by the PS 4000 antenna splitter via the antenna cables. For complex
systems with long antenna cables, we recommend powering each active antenna from a PSU 4000 cen-
tral power supply via an ASU 4000 remote power adapter.
The SRA1 is a remote UHF antenna with a hypercardioid polar pattern. The SRA1 will even operate per-
fectly as close to the floor or ceiling as 15 cm (6 in.). For details, refer to the SRA 1 User Manual.
The SRA 2 B is an active directional antenna with a rugged, water-resistant case designed specifically for
indoor and outdoor use at a distance from the performance area. An integrated high-performance anten-
na booster allows you to position the antenna up to 100 m (330 ft.) away from the receiver. Using RG213
antenna cables and two AB 4000 antenna boosters in series, you can set up the SRA 2 B even 200 m
(660 ft.) away from the receiver.
The antenna provides a BNC output, status LED, and integrated stand adapter. An optional laser point-
er makes it easy to align the antenna precisely with the performance area.
The RA 4000 B is an active omnidirectional antenna with a rugged, water-resistant case designed specif-
ically for indoor and outdoor use in close proximity to the performance area. An integrated high-per-
formance antenna booster allows you to position the antenna up to 100 m (330 ft.) away from the receiv-
er. Using RG213 antenna cables and two AB 4000 antenna boosters in series, you can set up the SRA 2 B
even 200 m (660 ft.) away from the receiver.
The antenna provides a BNC output, status LED, and integrated stand adapter.
1. Unscrew the four rubber feet (1) from the antenna splitter bottom panel.
2. Unscrew the two fixing screws (2) from each side panel.
3. Use the fixing screws (2) to screw the short bracket (3) to one side panel and the long bracket (4) to
the other side panel. The brackets are contained in the supplied rack mounting kit.
4. Install the antenna splitter in your rack.
1. Unscrew the four rubber feet (1) from each antenna splitter's bottom panel and remove the screws (5)
from the rubber feet (1).
2. Unscrew the two fixing screws (2) from the right-hand side panel of one antenna splitter and from the
left-hand side panel of the other antenna splitter.
3. Remove the plastic covers (3) from the side panels with the fixing screws (2) still on.
4. Insert one connecting strip (4) into each free slot in the side panel of the first antenna splitter, making
sure to align the hole in each connecting strip (4) with the appropriate threaded hole in the antenna
splitter bottom panel.
5. Fix the two connecting strips (4) on the first antenna splitter using two of the screws (5) you removed
from the rubber feet.
6. To join the two antenna splitters, slide the connecting strips (4) on the first antenna splitter through the
free slots in the side panel of the second antenna splitter. Make sure to align the hole in each con-
necting strip (4) with the appropriate threaded hole in the bottom panel of the second antenna splitter.
7. Fix the two connecting strips (4) on the second antenna splitter using two of the screws (5) you
removed from the rubber feet.
8. Screw a short bracket (6) to the outer side panel of each antenna splitter using for each bracket two
of the screws (2) you removed from the antenna splitter side panels.
9. Install the antenna splitters in your rack.
Be sure to keep the remaining screws (5) for later use.
The following hints on placing antennas apply to both single-channel and multichannel systems with any
number of channels.
