Using the ACA 1
Example 2: Large Church
The diagram represents a large Church such as a Cathedral. A
single pair of antennas is unable to provide seamless wireless
microphone coverage due to the size and complex shape of the
building.
Four diversity pairs of antennas are deployed in different areas
of the building at locations chosen by conducting a site survey.
50 ohm coaxial cables connect each antenna to a centrally
located ACA 1 combiner which feeds the radio signal from all of
the antennas to the radio receivers.
Boosters may be required on long cable runs. The ACA 1
provides 12V DC power at each input to power boosters or
active antennas as required.
Coaxial cable types must be chosen with care to avoid excessive
signal loss between the antennas and the combiner.
The type of antennas in each area should be chosen with care to
provide appropriate coverage.
