Installing the WA470 as an Antenna Combiner
The WA470 can be used to combine signals from four anten-
nas into the inputs of a single diversity receiver, while retain-
ing true diversity performance. This is particularly useful in
applications where two wireless systems must provide cov-
erage in adjacent areas. To install the WA470 as an antenna
combiner, refer to Figure 2 and proceed as follows:
6.Slide the WA470 into a 19-inch audio equipment rack.
7.Secure the WA470 to the rack with four screws and
washers.
8.Mount four half–wave antennas, two in each area, as
desired:
•
To wall mount the antennas, use the mounting brackets
supplied with the WA420 antennas.
•
To rack moutn the antennas, use a Shure WA440 Rack
Mount Kit.
•
To mount the antennas on microplhone stands, use
Shure A57 Swivel Adapters (or equivalent).
9.Connect each pair of antennas to WA470 connectors A
and B. Use Shure WA420 Antenna Cable or any 50
Ω
,
low loss antenna cable (RG–8x or equivalent).
10.Using the supplied interconnecting RF cables, connect
the WA470 output connectors to the antenna inputs on
the receiver, as shown in Figure 2.
