ACTIVE ANTENNA COMBINER KIT
The Audio-Technica ATW-49CB Active Antenna Combiner Kit includes two
dual-input, one-output Active Antenna Combiners designed for use with
Audio-Technica 4000 and 5000 Series UHF wireless receivers and ATW-A49
LPDA antennas.* Each Active Antenna Combiner is a broadband device
(frequency range from 440 to 900 MHz) that combines two incoming RF
signals into one outgoing RF signal. One set of Active Antenna Combiners
enables two sets of antennas to feed one wireless receiver or distribution
system. To compensate for RF signal loss associated with combining signals,
the Active Antenna Combiner provides unity gain. (Note that without the
use of an antenna preamplier, long antenna-cable length may deteriorate
signal.)
Each kit includes: two Active Antenna Combiners and two 45mm BNC-to-
BNC RG 58 coaxial antenna cables.
NOTE: The ATW-49CB Antenna Combiner requires +12V DC power from
any Audio-Technica 4000 or 5000 Series receiver or +5 to +14V DC from any
wireless receiver or antenna distribution system that offers antenna power.
A light on each Active Antenna Combiner indicates that power has been
correctly applied.
* The ATW-49CB Active Antenna Combiner Kit is also suitable for use with
other receivers that are in its specied band, use BNC antenna connectors,
and provide antenna terminal voltage; it may also be used with a variety of
other antennas from Audio-Technica and other manufacturers.
HOW TO INSTALL THE ATW-49CB ACTIVE ANTENNA COMBINERS
1. Connect one BNC-to-BNC RG 58 coaxial antenna cable (two supplied)
to the OUT connector on one Active Antenna Combiner (two supplied).
Connect the other end of this cable to the ANTENNA A input on either a
receiver or distribution amplier, as shown in Figure 1.
2. Repeat step 1 for the ANTENNA B input, using the second Active Antenna
Combiner.
3. Use coaxial antenna cables (not included) to connect the IN connectors
on each Active Antenna Combiner to a UHF antenna, as shown in Figure 1.
4. NOTE: ATW-A49 antennas do not require power. If you are using
ATW-A49 antennas, skip Step 4. If you have an antenna system that
requires power (such as an antenna preamp or booster) you must open
the ATW-49CB Active Antenna Combiner assembly and activate a switch
on the circuit board. (This enables the combiner to pass power through to
the antenna.) Current consumption of the preamp or booster should not
exceed 100mA.
The unit is shipped with the switch in the “off” position. To ip the switch
to the “on” position, first be certain the combiner is not attached to
any power source. Next, use a Phillips screwdriver to remove the two
screws on the Active Antenna Combiner’s access panel; remove the
access panel; use a tweezers to flip the switch into the “on” position.
Finally, replace the access panel and securely tighten the two screws. (See
Figure 2.)

有源天线汇合器套件
ATW-49CB是一套两路天线输入、一路输出的有源天线汇合器，
可配合鐵三角4000 5000及 系列无线话筒及ATW-A49偶极子天线使
用*。每个汇合器为宽频率元件 (频率范围由440至900MHz)，可把
两个射频输入信号汇合为一个射频输出信号，而一套汇合器可配
套一台接收机或一台天线分配器使用。天线汇合器内置有源放大
器，以补尝在汇合处理时的信号损失。 汇合器并没有天线前置放(
大器，过长的天线连接线会导致信号减弱)
套件内包括：两个有源天线汇合器，两条 长 接头45mm BNC-BNC
RG58同轴天线连接线。
注：ATW-49CB 4000 5000天线汇合 器需 要鐵三角 及 系列无线
接收机提供的 直流或其他无线接收机及天线分配器的 至+12V +5
+12V直流幻象供电。汇合器上设有显示灯，以显示是否正确供
电。
* ATW-49CB BNC天线汇合器可配套于其他在频率范围内，以
连接头及设有供电输出的接收机使用；另外，亦可配套于鐵三
角或其他型号的天线使用。
安装ATW-49CB天线汇合器
1. 使用一条BNC-BNC接头连接线，连接天线汇合器输出端到接
收机或分配器的 组天线输入。A
2. 使重复第1步骤，用另一条连接线，连接另一个天线汇合器输
出端到 组天线输入。B
3. 使用天线的同轴连接线，连接每个天线汇合器输入端到各个
天线。 图( 1)
4. 注：ATW-A49 ATW-A49天线不需使用幻象供电，如使用 天
线，可跳过此说明。如使用的天线系统需要供电 内置前置(
放大 器 或增 益器 ， 需 开启 汇合 器电 路 板内 的导 通 电 流 开)
关，使幻象供电电流通过汇合器传到天线上，而所提供的总
电流不应超过100mA。
汇合器的导通电流开关，预设为关闭 位置，需使用"OFF"
十字螺丝刀把底盖打开，再以小型一字螺丝刀把开关推至
开启 位置，然后再装回底盖。 图"ON" ( 2)
(设定前请先中断供电连接)
