Radio Broadcast Antenna Guide: FM, AM & SiriusXM Connectivity
Radio Broadcast Antenna Guide
Solutions for Crystal-Clear Analog & Digital Radio Reception, from FM/AM to Satellite SiriusXM.
1. Standard Radio vs. Satellite Radio
Broadcast radio technology varies significantly between terrestrial (FM/AM/DAB) and satellite-based systems (SiriusXM). Choosing the right antenna starts with understanding the signal source.
Terrestrial (FM / AM / DAB)
Signals broadcast from local towers. Requires whip or shark-fin antennas. DAB/DAB+ offers digital quality but requires specific frequency tuning.
Satellite (SiriusXM)
High-frequency signals (2.3GHz) from satellites. Requires a Small Magnetic Patch antenna with a clear view of the sky.
2. Common Connectors in Automotive Audio
Replacing a factory head unit or antenna often requires specific adapters. Use this list to identify your interface:
Motorola (DIN) Plug
The universal standard for aftermarket car stereos and FM/AM antennas.
Fakra A & B (White/White)
Standard for European cars (VW, BMW) for FM/AM diversity systems.
SMB / Curry Fakra
Exclusively used for SiriusXM and DAB+ digital radio receivers.
3. Maximizing Signal Clarity
Power Phantom Feed: Many modern car antennas have built-in amplifiers. If your new radio has poor reception, you may need a Phantom Power Adapter to inject 12V into the antenna cable.
Antenna Placement: SiriusXM antennas must be placed on the highest point of the vehicle roof with no obstructions to ensure continuous satellite lock.
Compatibility List
Compatible with aftermarket brands:
• Stereos: Sony, Pioneer, Kenwood, Alpine, JVC
• Satellite: SiriusXM Onyx, Commander, Onyx Plus
