power antenna

Good morning

I am new here and have been searching the form for an answer to a wiring problem. If it has nuts and bolts I am OK wires not so good. Here is my problem I have installed a Tri band extendable radio antena model 12355706 into a 1974 Charger I have rebuilt. This antena was used by GM in many vehicles. I want to control the antena using a switch (momentary switch I think) one position up and down in the other position with the switch resting in the center position. The antena has three wires grey, green and white. To make the antena go up grey is - and green is +.  To make the antena go down green becomes - and white becomes +. The green wire has to reverse polarity some how using a relay I think.

Can someone help me out on this with a diagram for the switch and relay as well as what kind of relay I need

thanks

5 pin electric window switch from Spal etc. no relay required or a 3 pin momentary with two timer relays such as the DEI 528t to make it automatic.
If you don't need it as an auto the the 5 pin switch is the cheapest option.

If the OP gave accurate information, the Spahl switch will not work. I will do some research to figure out what she needs to do. The Spahl switch will work if there were only 2 wires to control direction.

Purchase a fuse holder and some 5 amp fuses to place in the fuse holder.   Insert the fuse holder between your power source and all connections of the antenna.   Connect power to the white wire, Ground the chassis of the antenna. Touch green to power, the antenna should move one direction. Then touch grey to power, this should move the antenna the other direction.   Reread the first 2 sentences. If it works as above, it will be really easy to wire the relay to make it work.

Sorry Craig and OP, I read it whilst tired out, trying to find something to disable the starter in the latest Prius, what a PITA to get at the brake switch.

Ok I will check on powering the white and green wires in the morning, but If memory serves me right I tried this with no luck. I will let you know

Did you catch the part about the fuse holder and the 5 amp fuses?

Oh Yea fuses are a must

Ok as per post # 4 instructions which I printed and followed to the letter there was no antena movement. The only way I could get any movement was as I first posted grey - and green + for up and to go down it was green - and white +.         I don't want the antena up all the time so that is why I want a rocker switch.

Give me a minute. It will take a few relays. but it is possible.

Got there first Craig, you're at lunch and I'm finished for the day!:-

Definitely fuses on power and ground maybe diodes on switch feed?
Switch would be readily available, break before make, Farnel, Mouser etc.

Thanks I will build a mock up before install. I take it the black line in the down position represents the white wire?  What is the back of the switch going to look like?  The up position  will have a small jumper from 85 to 30.  In the down position there is a jumper from 86 to 30     Sorry to be a be so numb with wires. It will take a couple of days to get to the big city to pick up the bits and pieces. I will let you know how I make out

The black line in the picture goes to ground, see the symbol at the top? Yes it joins 85 and 30
Your white goes from 30 on the up relay to the antenna.
On the up relay 86 and 87 are joined then back to the switch.
The switch will have 3 terminals on the back, 12v (+) input, (-) ground
and green centre tap out to the relays.
Fuse both power and ground.

Thanks for the advice and help. I followed the diagram and the antenatal works like a charm. Just don't put the switch in the center off position until the antenna has completed its cycle or you just have to replace that fuse again and again.

Next will be possibly putting relays in the power windows to speed them up, they are dreadfully slow and some times don;t work at all using the factory wiring. They work fine if you bypass the factory stuff. I suppose since the car is a 74 the factory stuff might be getting weak\

thanks again

Try a non-silicone version of WD-40 sprayed into the window channels, relays aren't the answer.
Maybe the switch should have been post-natal. Did you have something else on your mind when you did your last post?

The window chanels have all been loobed with white lithium grease the kind used on snowmobile clutches. I was thinking relays so that the large power draw was not run through the switch. As it stands now the power comes to the switch and is then run to the window motor, through the switch. Nothing else on my mind when posting

OK then, you had the right idea for the first method, I wasn't being my normal, Non-PC chauvinistic self, you wrote antenatal instead of antenna!!!!
Before relays, new switches and definitely thicker cables with your POS (*) and NEG (-) straight to the battery.
