Phase II Aerial Information

[GlowRed]

I'm looking to replace my aerial with an active GPS aerial which also ideally has an FM antenna built in so I can use the existing car stereo.

Has anyone got a picture of a standard Phase II aerial showing the leads and connectors?

Does anyone know the number of leads from the aerial and what each one does?

Are there any redundant leads?

Any additional information would be very helpful.

Some of this old post might be useful

When I changed my aerial gasket there was a couple of wires on the aerial base just doing nothing.


Stuff about reception.

The display shows the radio reception information if you press buttons 1 and 6 simultaneously: 9 or letter: good reception–if 3: poor signal–if 2: no stereo
testing the buttons To enter this mode, press button 3 and the on/off button at the same time. Every time a button is pressed, it will appear on the display. The mode exits automatically once all the buttons have been pressed.

Carl, I've got a spare old base with the wires coming out but some of the connectors cut off IIRC. Can get a photo later if required?

If you could take a picture or two that would be great.

Carl, all I can tell you is it has 4 wires ( marked green, red & silver ) and a short one with what looks like a spade connector. If it's any more help the base is marked 'CALEARO' 0066-01.

May I ask you for what reason?

It seems you don't know a lot about this part so I'll start from the beginning. The base contains multiple parts as you can see on Phils pictures: AM/FM (Radio), GSM (Phone) and GPS. Thats what the colour coded cables are for, one cable for each. The fourth cable is connected to the chassis (ground) because thats quite an important component in radio/HF technology. The three cables are actually coaxials (a core, a shield and insulation). The shield I guess is self explaining, the core has two functions: Transmit the signal (bidirectional if required) and feed the unit with power. The result is a voltage overlay and is called phantom feeding. The power is used for the receiving, transmitting and amplifying circuits inside the base. The specs for all this technical stuff can be found in the secend link James provided. Also there is no redundancy.

Basically, I'm looking to connect a GPS unit to the car. The unit is supplied with a small GPS antenna which should be put on the roof of the car for best reception. I'm not happy with having a wire running across the roof running to a stuck on GPS antenna. I want a neat solution. Therefore I thought if I could replace the exiting antenna that would be a neat solution.

The GPS unit needs an active 3.3V GPS antenna. I have found an aerial with GPS and FM functionality and after speaking to the GPS unit manufacturer they think it will work.

So if I'm going to replace the existing antenna I don't want to lose any car functionality and I need to ensure I have the correct aerial connectors.

Fair enough.

The GPS unit needs an active 3.3V GPS antenna.

Too bad the original piece is not likely to work with this voltage.
