ATTB Flexible Passive Dipole AM FM Antenna

Antennentechnik Bad Blankenburg (ATTB) AM / FM Passive Dipole Antenna with 3.4m Cable (5001.02)

The ATTB 5001.02 is a flexible, highly effective passive dipole radio antenna engineered for clear, high performance AM / FM broadcast reception. Developed and manufactured in Germany by Antennentechnik Bad Blankenburg, ATTB has stood for premium quality and radio networking reliability since 1919. Equipped with a generous 3.4 metre integrated RG 174 cable and a standard ISO male plug (adaptor may be required depending on your radio connection), it provides a simple, uncompromising solution for vehicle retrofits, retro car audio restorations, situations where the original factory aerial can't be used or repaired, caravans, motorhomes, and custom installations.

Why Choose a Dipole Antenna Over Standard Roof or Glass Antennas?

• No Metal Ground Plane Required: Standard car aerials require a solid metal roof or panel to act as a ground plane to function properly. As a true dipole antenna, the 5001.02 operates entirely independently of metal grounding, making it the ultimate choice for self stable plastic, fibreglass, wood, or composite structures (such as caravans, motorhomes, boats, trucks, and classic cars).
• Hidden / Interior or Outdoor Installation: Suitable for both indoor and outdoor applications. Unlike external roof mounted whips that are vulnerable to vandalism, low clearance branches, or car wash damage, this flexible dipole can be discreetly mounted inside A pillars, behind plastic bumpers, inside roof liners, under dashboard trim, or attached via cable ties or clips. Avoid shielding the aerial by metal.
• Passive & Power Free Operation: Requires no 12V power connection or turn on signal, making installation quick, reliable, and free from electrical amplifier noise or power drain.
• Superior Performance Over Glass Sticky Antennas: Traditional glass mount patch antennas are often degraded by heated wire demisters, metallic window tints, or poor grounding. The ATTB dipole design maintains a balanced reception profile regardless of glass treatments.
• Ideal for Vintage & Classic Radios: Unlike active amplified aerials that can cause RF overload, cross modulation distortion, or muffled audio on sensitive analogue tuners (such as original 1960s and 1970s factory radios), this passive dipole delivers a clean, unamplified signal.
• Zero Electrical RF Noise: Powered amplified aerials can pull high frequency switching noise directly from a vehicle's electrical system into the tuner. Being completely passive, this dipole requires no 12V power feed, ensuring zero injected electrical interference or alternator whine.
• Wide Compatibility Range: Provides the exact balanced signal profile required by delicate vintage receivers while maintaining excellent, clear reception for modern aftermarket head units.

Key Features & Technical Highlights:

• Made in Germany Quality: Designed and manufactured in Germany by Antennentechnik Bad Blankenburg under strict testing processes for first class reception even under difficult conditions.
• Broadband Radio Reception: Optimised for global broadcasting across AM and FM frequencies (0.15 to 108 MHz).
• Integrated 3.4 Metre Cable: Factory fitted with an approximate 3.4m low loss RG 174 coaxial cable, providing ample length to route from hidden mounting locations straight to the dashboard head unit.
• Universal ISO Plug: Terminated with an Euro-style ISO male connector (50 Ohms / ISO 41585 / ISO 10599). Adaptors may be needed and are optionally available.

Installation Guidance:

• Mounting Position: Selecting an elevated mounting position (such as a roof structure, upper interior trim, or high panel) is preferable.
• Antenna Orientation: The antenna element should be installed in a largely straight, elongated shape or at a 90° angle starting from the feed point.
• Cable Routing: Avoid routing the connecting cable parallel to the main antenna conductors. Keep a minimum clearance distance of > 10 cm from the element.
• Securing: Can be wedged in place or secured using cable ties, clips, or suitable mounting hardware. Avoid using metallic mounting items.
