INSTRUCTION MANUAL
WALL-MOUNTED WIRELESS ANTENNA
YW-4500
Please follow the instructions in this manual to obtain the optimum results from this unit.
We also recommend that you keep this manual handy for future reference.
1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section carefully before use.
• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
• We also recommend you keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual fi rst and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
• Be sure to securely mount the unit on the wall or ceiling that is robust enough to stand the antenna weight.
Failure to do so may drop the antenna, causing personal injury and/or property damage.
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing
so may result in fi re or electric shock.
• To prevent lightning strikes, install the unit at least fi ve meters away from a lightning rod, and yet within the
protective range (angle of 45º) of the lightning conductor. Lightning strikes may cause a fi re, electric shock or
personal injury.
• Since the unit is designed for in-door use, do not install it outdoors. If installed outdoors, the aging of parts
causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of
electric shock.
• Use nuts and bolts that are appropriate for the ceiling's or wall's structure and composition. Failure to do so
may cause the unit to fall, resulting in material damage and possible personal injury.
• Do not touch a plug or antenna during thunder and lightning, as this may result in electric shock.
• Leave the installation of an antenna to your TOA dealer because the installation requires expert knowledge.
The falling of an antenna may cause personal injury.
• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury
and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

2. GENERAL DESCRIPTION
The TOA YW-4500 is an indoor dipole antenna designed to be used in a UHF band wireless system. A power
lamp is provided on the unit's bottom side to indicate the power supply status (it lights when power is supplied.).
Power for the YW-4500 is supplied on a coaxial cable from the antenna connector of the WT-5800, WT-5805,
WT-4820, or WD-4800.
Cable loss can be compensated for by a built-in RF signal booster.
3. INSTALLATION PRECAUTIONS
• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or steam.
• When installing the YW-4500 in a room of a tall building, be sure to position it more than 1 m apart from a
window to minimize interference caused by external noises of radio waves.
• When using a wireless microphone, keep it 3 m or more away from the YW-4500.
Doing otherwise may cause unused other channels to operate or radio interference to occur.
• When using two or more antennas, they should be spaced out 6 to 18 m apart from each other.
• Take special care when treating coaxial cable end and when connecting the cable to the antenna and
BNC connector. Incomplete cable treatment and connection deteriorate receiving sensitivity, and increase
interference caused by external noises.
• Use the coaxial cable of 75 Ω impedance.

Step 3.
Strip coaxial cable end.
• RG-6/U
• RG-11/U
Step 2. Detach the top case from the bottom case.
• If the coaxial cable is wired over the wall from the
ceiling or floor
1. Cut the cable outlet of the frame using a pair of
cutting pliers, etc.
3. Run the coaxial cable through the cable outlet.
5. INSTALLATION
Unit: mm
• If the coaxial cable is to be drawn directly from the
wall surface
1. Drill a ø20 mm hole.
2. Run the coaxial cable through the hole and the
bottom case as well, and draw it out as shown
below.
• If the coaxial cable is installed using a recessed
electrical box (Mounting pitch: 83.5 mm)
Draw out the coaxial cable through the electrical
box and the bottom case.
Note: Be sure to use a pipe thick enough to allow
the wired coaxial cable to be easily inserted.
Step 1.
Remove 4 screws on the top case.
2. Cut the supplied rubber bushing into halves. One
half is suited for the RG-6U cable (smaller internal
diameter) and other half for the RG-11/U cable
(larger internal diameter). Run the cable through
the bushing. (Insert the bushing into the cable
entry hole after cable installation completion.)
