Frequently Asked Questions - AA 03 ZEHNDER

How do I install the Zehnder AA03 antenna?

First, insert the stand pole into the hole on the back to keep it upright. Then connect one end of the supplied IEC cable to the antenna's IEC port and the other end to your DVB-T receiver. Next, connect the power adaptor (9V DC) to the antenna's DC jack and plug it into a mains outlet. If your receiver provides 5V DC via the coaxial cable, you may skip the power adaptor. Finally, connect your receiver to your TV via SCART cable and turn on both devices.

Can I use the antenna without the power adaptor?

Yes, if your DVB-T receiver supplies 5V DC through the coaxial cable (e.g., Zehnder TX 60). You must then enable the antenna power supply in the receiver's setup menu.

How can I improve reception if I get interference?

Try rotating the antenna slightly or changing its polarization (tilt it sideways between horizontal and vertical). Also, move the antenna to a different location, ideally near a window. Check the reception level and signal quality using your receiver's setup menu.

What is the difference between horizontal and vertical polarization?

Polarization refers to the orientation of the antenna elements. The AA03 can be used in either position. Switching between horizontal and vertical can help reduce interference or improve signal strength depending on the broadcast polarization in your area.

Does the antenna work for FM or DAB radio?

Yes, the AA03 is designed to receive DAB (digital radio) as well as DVB-T TV signals, as it covers the VHF and UHF frequency range (47-860 MHz).

What should I do if the signal is too strong (near transmitter)?

If you are very close to a transmitter, a too-high signal level can cause reception problems. In that case, avoid placing the antenna near a window or try moving it to a less exposed location.

How do I clean the AA03 antenna?

Always unplug the antenna from power and the antenna cable before cleaning. Use a soft, slightly moistened cloth to wipe the casing. Do not use any solvents or abrasive cleaners.

Can I use this antenna with a satellite receiver?

No, the antenna is intended for terrestrial DVB-T/DAB reception only. Do not connect it to a satellite receiver, as that may cause damage or improper operation.

Is the included coaxial cable long enough?

The antenna comes with a 2-meter IEC-to-IEC cable. This should be sufficient for most indoor setups. If you need a longer cable, you can use an extension, but it may affect signal quality.

What does DVB-T stand for?

DVB-T stands for Digital Video Broadcasting – Terrestrial. It is the standard for digital terrestrial television transmission. The AA03 is optimized to receive these signals.

Digital Indoor Antenna

AA03 was specially designed to receive digital terrestrial TV signal as well as radio programs (DVB-T, DAB) in the VHF- and UHF-frequency range at indoor use.

The metal-silver, flat and stylish housing is a perfect match for your modern TV set and your modern styling living room.

Features

• Active antenna with embedded amplifier
- Friendly Advanced design for either Horizontal or Vertical position
• complete VHF/UHF wide band range reception 47-860 MHz (CH 02-69)
- Low noise figure by using high-quality components
• Built-in filter against GSM signal interference
- Convenient Powering System – two ways selectable either with power adaptor or with DVB-T receiver

Accessories attached :

1) Antenna AA 03
2) Stand pole
3) Power adaptor 9VDC/50mA
4) IEC to IEC antenna coaxial cable, 2m

Installation (Please refer to illustration):

Step 1. Take the pole attached, and then plug into the hole shown in illustration to keep it standing.

Step 2. Take the IEC cable attached, and then connect one end to the IEC port, and the other end to your DVB-T receiver shown in illustration Attention! Don't connect to a Satellite-Receiver!

Step 3. Take the power adaptor attached and Insert the end of DC connector into DC jack on the back of AA03, and then plug in the A/C end.

***** If your DVB-T receiver (e.g. Zehnder TX 60) supplies with 5 VDC from IEC connector, then it is not necessary to use the power adaptor.

Step 4. Connect your receiver and your TV by Scart Cable (see receiver manual) and switch them on.

***** If your DVB-T receiver supplies with 5 VDC, ensure in the set-up menu of the receiver, that the power supply to the antenna via the coax cable is switched on.

Tips for correct Antenna Adjustment

To verify the quality of reception, you can use either the TV picture or the option of displaying the reception level and signal quality in the set-up menu of your receiver.

If reception is subject to interference, turn the antenna slightly, or alter the direction of polarisation by titling it sideways (horizontal – vertical), and check the quality of reception.

If it is impossible to get optimum reception, set the antenna up in a different place (we recommend a position close to a window), and repeat the steps described above.

Location and Installation Notes:

• Operate the antenna only at dry indoor places.
• Rooms with windows are the most suitable locations to get best reception quality with sufficiently high signal level.
• Do not subject it to direct sunlight for longer periods, because material can change for the worse.
• Do not place the antenna close to heaters or naked lights (e.g. candles). There might be a danger of fire!
• Place the antenna on a safe and firm ground.
• Protect the device from moisture, drips and splashes.

Cleaning

Before cleaning, unplug the antenna from power and antenna cable. Use only a soft and slightly moistened cloth to clean the casing.

Operation Notes:

• In areas with low or too high reception-field strength, interference-free reception is not always guaranteed. If the signal level is too low, a directional antenna should be placed outside the building.
• In the immediate vicinity of the transmitter, reception may be impaired by a too high reception level. In this case, you should avoid setting up the antenna near a window.
• Indoor radio reception can also be impaired by other factors:
• rooms in reinforced concrete buildings
• rooms with vapour-plated windows
• in positions directly beside transmitting electronic devices (e.g. mobile phones)
