Seeking help: Panasonic motor antenna

Post by T-Modell » Fri 02 Oct, 2015 6:22 pm

Hi guys,

as you sometimes have Japan Imports ... my donor SL had this Panasonic antenna. I have no idea what the extra box and the four cables are for. Nothing is moving and a Hirschmann antenna is much simpler. I couldn't find anything online, so can you tell me how this works? What are the cables for? Is that Japan-specific?

I saw something similar in a Japanese market 230TE I wrecked. I'm guessing the small box is a signal amplifier.
It looks like only 3 wires are connected externally and I'd say they are the same three wires that you would connect to a Hirschman:
  • +12V constant
  • Remote switch-on (from head unit)
  • Ground
(Edit) That's probably rubbish as there's no co-axial connection into the box. Perhaps it's just the switching relays mounted externally?

Thanks,

there's four wires coming out of the antenna (Ground's extra) and going into the box. There's three wires from the box and the ground is on the base of the antenna (where it's mounted to the body of the car). Nothing moves, when I put 12V on any of the cables ...

Easiest thing would be to take the cover off the antenna (if possible) and see where those four wires go to. I'd assume they go to end-position switches, which leaves the box to switch on and off the motor in the correct direction, depending on the position of those switches. So, that would be a connection for (1) Top End Position, (2) Bottom Postition, (3) 12v and (4) Gnd to motor.

To get it to extend, you need to put 12V to TWO of the external connections (i.e. the constant 12V and remote sensing wires), then when 12v is removed from the remote wire, the antenna retracts.

OK thanks, I left the box connected and - of course - by connecting the two cables to 12V the antenna extracted ... but putting 12V on ONE of the connections doesn't retract it ... must be something with those end switches. When I continue to put 12V on both ends, the motor still tries to extend the antenna, but it's completely out. So maybe the end switches?

Hi,

I've found how it works: As you see on the picture, the black wire is ground, the yellow wire has 12V permanent. When I connect the white to the yellow wire (12V), it moves out, but I have to connect it to the black wire (ground) to move in again ... shouldn't it retract, when the 12V are "just missing"?

P. S.: I took the little cover off; this disc is turning between two contacts when the antenna is moving ... so that controls the end positions.

As the antenna signal cable is completely separate from the box, I don't think that. Maybe it controls the on/off of the antenna. Later I try to open that box ...

But everything I found so far works like you described, 12V on -> out, no voltage at all -> in ... strange

Edit: It works, my fault. I tested it with a radio and it works the correct way. First thinking, then posting :banghead:

Thanks anyway!

Thanks,

just to finish that off: The little box houses the circuit to control the antenna (which is in the housing with Hirschmann antennas).

I've cleaned the antenna, put a bit of oil on it and it works fine. Another 100 Euros saved for my project :occasion5:
