Product Information
Full details
The AS2611 Active Antenna Splitter by Antennentechnik Bad Blankenburg is designed for vehicle owners looking to integrate or maintain high-quality FM and DAB+ digital radio reception. This device serves as a signal amplifier that distributes a single antenna input into two outputs, ensuring clear audio and consistent signal integrity for car audio enthusiasts. While the unit is highly effective at boosting signal strength for multi-tuner setups, users should note that proper installation requires basic automotive electrical knowledge to ensure constant power delivery to the integrated amplifier.

FAQs
Does the AS2611 require external power?
Yes, it is an active splitter, meaning it requires a 12V connection to power the internal signal amplifier.
Can I use this for FM radio only?
Yes, it is backward compatible with FM, but it is specifically engineered to handle both FM and DAB+ bands.
Will this work with passive antennas?
It is designed to work with standard automotive antennas, though effectiveness may vary based on the antenna's base quality.
Where should I mount the splitter?
Mount it as close to the radio head unit as possible to minimize signal loss, away from high-voltage cables.
Does it improve existing signal quality?
It prevents signal degradation caused by splitting; it is not a signal 'booster' that will turn a completely dead signal into a perfect one.
Is this compatible with all car radios?
It is compatible with standard automotive radio systems that utilize standard coaxial antenna plugs.
Troubleshooting
Weak signal or no sound from radio
Verify that the 12V power supply wire is connected and receiving voltage when the ignition is on.
Intermittent audio or static
Inspect all coaxial connectors for loose pins or damaged shielding; ensure the unit is grounded properly to the vehicle chassis.

Setup, Compatibility & Care
To set up the AS2611, ensure that the antenna input is securely connected from your vehicle roof mount. Connect the two outputs to your respective radio tuner inputs. Crucially, the unit requires a 12V switched ignition source to power the internal amplifier; connect this wire to the 'remote turn-on' lead of your head unit or a switched fuse box circuit. Avoid mounting the unit near high-current wiring, such as fuel pump or amplifier power cables, to prevent noise injection. Periodically check that all coaxial connections are tight and free of corrosion, especially if the device is mounted in an area prone to humidity.
