Learn what Fakra Z adapters do, how to choose between 30cm, 5m, and 6m cables, and when male-to-female or female-to-female fits your setup.
Quick Answer
Choose a Fakra Z adapter based on the gap between your antenna and device: 30cm for tight spaces, 5m for standard car runs, and 6m for longer routes. Match the connector gender to your existing plugs.
Why Fakra Z is the common choice
Fakra Z is one of the most widely used connector codes in car antennas and aftermarket head units. It carries GPS, GSM, analog and digital radio (DAB), and TV (DVB) signals through a single standardized plug, which is why you see it on many universal aerial kits.
The 'Z' code refers to the keying and color of the connector shell. It is not a signal type – it simply ensures the plug fits only the matching Fakra Z socket, reducing the chance of plugging the wrong cable into the wrong port.
Length trade-offs: short vs long cables
A 30cm cable is ideal when the antenna and device sit close together, such as behind a dashboard or in a center console. It keeps the run tidy and avoids excess cable that can cause signal loss or clutter.
Longer cables like 5m or 6m give you flexibility to route the antenna to a rear window, roof, or wing. The trade-off is potential signal attenuation over distance, though for typical car installations the difference is minimal with quality cable.
Connector gender: male vs female
Fakra cables come in male (plug) and female (jack) ends. To extend an existing cable, you usually need a male-to-female adapter – one end plugs into the antenna, the other into your device. If you need to join two female-ended cables, a female-to-female coupler is the right choice.
Check the ends of your current antenna and device. If both are female, you need a male-to-male cable – but note that the CEN cables listed here are male-to-female or female-to-female only, so verify your setup before ordering.
Fakra Adapter FAQ
- What is a Fakra Z antenna adapter?
- A Fakra Z adapter is a standardized connector cable that links an antenna to a device like a car stereo, DAB receiver, or TV tuner. The 'Z' code ensures a secure, keyed fit. Check the connector code on your existing equipment – if it's not Z, a different Fakra code may be needed.
- How do I choose the right cable length?
- Measure the distance between the antenna base and the device input. Add a little slack for routing. Use 30cm for short, direct runs; 5m for typical front-to-rear installations; 6m for longer routes or larger vehicles. Always measure the actual path, not just the straight-line distance, to avoid ordering too short a cable.
- Male-to-female or female-to-female?
- A male-to-female cable extends an existing male antenna plug to a female device socket. A female-to-female coupler joins two male-ended cables. Check both ends of your current setup before buying. If you have two female ends, you need a male-to-male cable – not listed here – so verify your connectors carefully.
- Will these cables work for GPS, GSM, DAB, DVB, and TV?
- Yes, the CEN Fakra Z cables are designed to carry all these signals. The cable does not differentiate between them; it simply passes the RF signal from the antenna to the device. No need to buy separate cables for each service – one Fakra Z cable can handle multiple signals if your device supports them.
CEN Fakra Z Cables at a Glance
- Fakra Z Antenna Aerial 5m Extension Cable Male to Female GPS GSM DAB DVB TV: 5m Fakra Z extension cable, male to female, supports GPS, GSM, DAB, DVB, and TV. This is the most versatile length for standard car installations where the antenna and head unit are not adjacent.
Fakra Z Antenna Aerial 5m Extension Cable Male to Female GPS GSM DAB DVB TV - Fakra Z Antenna Aerial 30cm Cable Male to Female GPS GSM DAB DVB TV: 30cm Fakra Z cable, male to female, supports the same signals in a short run. Ideal for tight spaces like behind the dash, minimizing cable clutter and potential signal loss.
Fakra Z Antenna Aerial 30cm Cable Male to Female GPS GSM DAB DVB TV - Fakra Z Antenna Aerial 6m Extension Cable Female - Female GPS GSM DAB DVB TV: 6m Fakra Z extension cable, female to female, supports the same signals. Use this when you need extra reach for rear-mounted antennas, but ensure your existing cables have male ends to connect.
