YW-4500
WALL-MOUNTED WIRELESS ANTENNA
INSTRUCTION MANUAL
• 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 fire or electric shock.
• To prevent lightning strikes, install the unit at least five meters away from a lightning rod, and yet within the
protective range (angle of 45°) of the lightning conductor. Lightning strikes may cause a fire, 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.
1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section carefully before use.

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, WT4820, 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 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.

• 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.)

Step 4. Fix the coaxial cable to the circuit board of
antenna.
1. Remove 3 cable clamp screws.
2. Connect the coaxial cable to the circuit board.
3. Fix the cable with the removed screws.
Step 5. Mount the antenna bottom case on the wall.
Use the supplies wood screws (4 x 25) to fix it to the
wall surface, or supplies machine screws (3.5 x 20) to
fix to the electrical box.
Notes
• When installing the YW-4500, be sure the antenna is
more than 30 cm away from the ceiling. It is
recommended that the unit be installed at the height
of 2.4 m or more from the floor.
• Set the antenna vertical to the ceiling floor. The
receiving sensitivity of the antenna, when installed
horizontally, is about 6 dB lower than that when
installed vertically. The receiving sensitivity greatly
depends on the installation condition.
Step 6. Replace the top case and retighten the 4 top
case screws removed.
In this case, pay attention to the following points.
• The top case should be positioned with its lamp hole
(located on the bottom side) facing downward.
• The knob of attenuator switch on the built-in circuit
board should fit in that of top case.

6. SPECIFICATION OF THE COAXIAL CABLE
7. ATTENUATOR SWITCH SETTING
The attenuator switch is provided to minimize external noises or interference caused when two
or more microphones having the same channel or adjacent channels are used in close proximity
to each other.
The attenuation level can be selected from 0 (factory-preset), –10, and –20 dB positions.
The more the attenuation level increases (antenna sensitivity becomes less), the narrower the
usable area of wireless microphone is.
In the condition that no interference is present, set the attenuator switch of the antenna for 0 dB position.

Bedienungsanleitung
• Die Antenne darf niemals direktem Regen ausgesetzt werden. Aufstellorte, an denen die Antenne mit Wasser
oder anderen Flüssigkeiten bespritzt werden kann, sind zu vermeiden. Nicht in feuchten oder staubigen Räumen
installieren, nicht direktem Sonnenlicht aussetzen oder in unmittelbarer Umgebung einer Heizung anbringen.
• Befestigen Sie die Antenne an einer stabilen und tragfähigen Wand. Achten Sie darauf die zur Wand passenden
Befestigungsmaterialien auszuwählen.
• Die Antenne sollte in einen Mindestabstand von 5 m zum nächsten Blitzableiter installiert werden.
• Service- oder Reparaturarbeiten dürfen nur durch authorisiertes Fachpersonal durchgeführt werden.
• Hängen Sie keine Gegenstände an die Antenne.

2. ALLGEMEINE BESCHREIBUNG
Die Antenne YW-4500 ist eine Dipolantenne für Innenräume und wird in Kombination mit UHF-FunkmikrofonSystemen eingesetzt. An der Unterseite befindet sich eine Betriebsanzeige, die leuchtet sobald Spannung anliegt.
Die Spannungsversorgung erfolgt entweder vom Antenenverteiler WD-4800 oder dem Empfänger WT-5800, WT5805, WT-4820, über ein BNC-Kabel. Die Antenne kompensiert Kabelverluste über eine HF-Signalverstärkung.
3. VORSICHTSMAßNAHMEN BEI DER INSTALLATION
• Um störende Interferenzen zu vermeiden, sollte bei der Installation ein minimaler Abstand von ca. 1 m zum
nächsten Fenster eingehalten werden.
• Die Vorteile eines Diversity Systems kommen erst bei einem Mindestabstand von 3 m zwischen Mikrofon
(Sendeantenne) und Empfangsantenne zum Tragen. Andernfalls besteht die Gefahr, dass es zu Interferenzen
oder dem Ansprechen nicht verwendeter Kanäle kommt.
• Zwei Empfangsantennen sollten 6 bis 18 m Abstand zueinander haben.
• Zum Anschluß bitte ein Koaxkabel mit 75 Ω Impedanz verwenden.
• Das BNC Kabel schirmt Einstreuungen ab, sofern es korrekt konfektioniert und angeschlossen wird.
• Die Reinigung sollte mit einem feuchten Tuch erfolgen. Verwenden Sie keine Lösungsmittel, wie Benzin oder
Verdünner oder andere leichtflüchtige Flüssigkeiten.
