Specifications are subject to change without notice.
The ATW-B80WB consists of a pair of UHF wideband powered in-line antenna boosters,
designed to increase the RF signal strength to compensate for antenna cable loss. When
paired with the appropriate UHF antennas the boosters are especially suited for applications
where there are long RF cable runs between the antennas and receiver locations.
470-990 MHz
Engineered for temporary or permanent installations, the boosters are designed to work
with the half-wave antennas supplied with 3000 and 6000 series receivers and the
ATW-A49 LPDA antenna. Each booster contains an integral RF amplifier powered by
12V DC provided on the antenna cable by the associated wireless receiver or antenna
distribution system. Power is required for their operation and a power active indicator
illuminates when power is applied. Wideband filters on the boosters minimize the
amplification of unwanted RF signals. A gain setting button permits selection of +12 or
+6 dB operation, to compensate for cable losses or other operating conditions. Inputs
and outputs are via standard BNC-type connectors. Constructed of metal to minimize the
pickup of RF interference, the boosters are a stainless steel finish.
Architect’s and Engineer’s Specifications
The in-line RF booster set shall consist of two UHF wideband RF boosters for permanent
or portable applications. Each RF booster shall be wideband filtered for operation as
determined by the associated wireless systems and an internal RF amplifier designed to
drive long cable runs between the antenna and receiver. Amplifier gain shall be selectable
at +6 dB, +12 dB via side-mounted button. The antenna shall operate on 12V DC power
supplied via the RF cable from an associated wireless receiver or antenna distribution
system. Each antenna shall draw no more than 60 mA of current; an indicator light shall
be provided on the antenna to show power is present. DC power shall pass through the
device to feed other powered RF devices attached to the booster. RF input and output
connections shall be via standard BNC-type connectors. Each in-line antenna booster shall
be constructed of metal and have a stainless steel finish.
The Audio-Technica ATW-B80WB for systems operating in the 470–990 MHz band is specified.
