Thanks Tom , I get your point in the differences of the two antennas. |

PS, Magoo,
I cannot speak for the configuration of Russ's antenna, but the Hirshmann I have and, I think other unmodified automatic antennas will not work with the 308 semi-automatic circuit and console switch. You could connect one of the poles of the console switch to the green, "extend" wire, move the switch to that pole and extend the mast, but, as soon as you let off of the switch (opening the circuit), the mast would retract.

Magoo,
How many times can Russ overrun his antenna, and the clutch not become loose? While driving my 308, I can neither see nor hear the antenna operating, so I would have to guess when to let up on the switch. Would that be zero or 30 seconds after full extension or retraction? I rarely use my radio, anyway, so it doesn't even matter for me, but I like the limit switch feature rather than the motor straining for no purpose. Maybe the better quality antennnas have limit switches. |

So it is basicly the same antenna Russ has with a clutch except yours goes off after 2 revolutions and his continues with his finger on the switch. Frankly I don't see the importance of your antenna over the other one. All Russ has to do is take his finger off the switch. BRGDS, |

Magoo,
The Hirschmann 2030 antenna that I used has a simple limit switch inside that is rotationally connected to the extend/retract motor and is timed to open the motor circuit when the antenna mast has reached either of its extremes. The timing is not exact: the antenna will continue to make noise for 1-2 seconds after the antenna mast is fully extended or retracted, so I suspect there is also some sort of clutch between the motor and the mast. Check out PRANCING HORSE No. 131, page 44, if you have it. |

Thomas so what you are saying is that there is no clutch to slip at the end of travel? Or just doesn't have a clutch and is straight drive which cuts off at the end of the travel. |

What's the antenna used for?

See my article in "Need help troubleshooting power antenna on 308QV" on converting a modern power antenna for use with the 308 console switch. I used a Hirschmann Model 2030 and rewired it internally to be compatible with the original 308 circuit. This particular antenna, and, I think, most others available today, has a limit switch that causes the motor circuit to open 1-2 seconds after the antenna mast reaches the desired end of its travel. The console switch can then be held in that position but no further activity inside or outside the housing of the properly modified antenna will occur. |

There are 2 types of elect. antenna's. Automatic and semi-automatic. If it has a switch it is semi-automatic and will keep running as long as you press the switch. Automatic works with the radio. When you turn it on it goes up and stops. If you want to take out the switch you need to run extra wires back to the new replacement ant.Also you need to make sure that your radio has a wire designated for an elect. ant. |

stop automatically, lol. These cars are not know for there antenna design. |

Russ: I just went out and checked mine. Does the same thing. No problem, just the way it is. (89 328 gts) |

To raise the antenna I press the rear part of the antenna button. It then goes up but does not stop when raised fully. It just chatters at the upper limit until I let off on the button. Is this normal. Seems to me that it should stop automatically when fully raised or retracted. Any thjoughts on this would be appreciated. |
