Icon5 Power Antenna & Stock Spoiler Clearance Issue

Hey Guys, I installed a stock year-correct spoiler in the stock location and I also just recently replaced my Power Antenna mast. If I open the trunk with the antenna up (Radio on), the spoiler hits the antenna. I can push the antenna over a little to clear the spoiler but I'm afraid i'll forget that one time and break it.

Do any of you have this issue? Could the Power Antenna assembly simply be misaligned? Everything seemed to fit right into place when I reinstalled the assembly.

I was also wondering if there might be a circuit to interrupt the Power signal when the trunk is opened? If not, I'm going to make one for mine!

Re: Power Antenna & Stock Spoiler Clearance Issue

It's a common issue for people who add a spoiler to a 3rd gen that didn't originally come with one. Mine came with a spoiler, and there are more wires going to the antenna that will lower the antenna when the trunk lid is opened. Yours doesn't have this provision in the trunk wiring harness so you'll need to either turn off the radio or move the antenna with your hand when you open and close the trunk. I don't know if you can add these wires to the harness or not. The main wiring harness may actually have the wires for this but you'd have to look. Also, the antenna has a different connector with more conductors if it was equipped with a spoiler, so you'll need to figure out how to add that to your antenna if possible.

My solution on a different 3rd gen I used to own was to just delete the main antenna and use the one in the rear window. Worked fine for me, and I didn't have to worry about braking the mast anymore.

Re: Power Antenna & Stock Spoiler Clearance Issue

Kool, Thanks for the info and verification. I figured if Honda was smart enough to add a sensor to tell you when a light bulb burned out that they'd have known to add a circuit to lower the antenna when you pop the trunk.

It will be pretty easy to build a circuit to make the antenna go down when the trunk is popped. I will need a normally open switch, some wire, and if I can get my hands on them, a stock male and female connector, just like the ones that go on the Antenna and harness. If not, I'll have to cut and splice the remote antenna wire.

How the circuit will work is: When the Remote Power is removed from the Antenna, it goes down. So I'll position the switch so it is pushed in when the trunk is closed, completing the circuit and the antenna will operate normally. When the trunk is raised, the circuit will be broken, just as if the radio (or the car) was turned off and the antenna will go down. When you close the trunk, it will come back up, just like the stock circuit.

BTW... Do you know if anyone sells "Honda" connectors anywhere online? I'll do a search, just wondering if you had a tip as where to start.

Once I get it finished and installed, I'll add a How-To with pictures of everything and links to where I bought the parts.

Re: Power Antenna & Stock Spoiler Clearance Issue

OR...

I could use the power that turns on the trunk light, to also turn on a relay, that disconnects that Remote Power from the Power Antenna... Hmmm...

Maybe that's how Honda did it on the stock circuits?!

Re: Power Antenna & Stock Spoiler Clearance Issue

Haha, I can hear your creative wheels turning.

I'm not really sure how the stock system worked. I never looked into it, but I remember seeing a switch in the latch mechanism when I replaced the rear pan on my current 3rd gen. Not sure if that's for the light or the antenna though. Or it could be for both.

Re: Power Antenna & Stock Spoiler Clearance Issue

Yeah, I need to look into how the trunk light is turned on. Some of the old cars had a mercury switch like in the old thermostats with 2 contacts... The tilting of the trunk lid would cause the light to turn on and off.

Another "trick" I have been mulling around in my head is how to make a Manual control circuit for the Power antenna to where you can make it go half mast or anywhere between. I saw that some of the later model Preludes have this and thought it'd be a great upgrade to my car.

I have the circuit figured out, It's easy if I add a push button to turn on and off the Manual circuit, but I wanted a "cleaner" setup with just the rocker switch. It's how to use just 1 Rocker switch and STILL be able to set it back to "Full Auto" operation. I COULD use a relay that turns on and latches when you use the Manual switch and stays on and until you turn off the car (or the radio) cause it would be latched with the Remote Power wire. Then the circuit would return to normal until you "Manually" adjusted the antenna again.

And I am planning on putting the rocker switch INSIDE the stock dimmer switch/knob assembly, providing there is enough space.

What do you think?

Re: Power Antenna & Stock Spoiler Clearance Issue

Same year accords have antenna switches in the console...and 3g consoles have a place for them.
I was gonna do one on each side of my shifter. One as a kill switch, the other to lower the antenna when listening to cd's or my mp3 player.

Re: Power Antenna & Stock Spoiler Clearance Issue

There was actually a switch in JDM 3rd gens for lowering the mast to half height. The JDM antenna mast is extremely long when paired with this switch, so I can see why there was a switch for this. I've never seen one myself, but I have seen pictures. Even with this switch, I'm not sure it would be low enough to clear the spoiler at the half way point. But with some testing you could probably find a point where it would clear and adjust it to lower to that point.

I know that others have had this issue in the past. Most replace the antenna with a shorter more flexible non-powered one. So there may be some people who would want to buy this if it would allow them to keep the stock style power antenna.

wait. theres an antenna in my rear window? how i use it? I just manually raise and lower my antenna when i open the trunk after adding an antenna. most the time i just leave that stupid antenna down because it makes my car look like an rc car with it up

That is a good use of space and pre-cut holes! It would make the install so much cleaner and possibly easier. I'll have to see if the OEM switches will work.

I will have to find out if this switch will work with my circuit AND if they are still available! When I build this, I will make 2 versions, one for those whose antenna already lowers when the trunk opens and one with the MOD to make it to where it will. That way if you have it at half, it'll lower all the way. But you'll have to reset the height yourself if you open the trunk.

Yeah, I will initially build this to work with the OEM Power Antenna, since that is what I have. I'll post a thread to see if anyone is interested and "take orders" if so... If there are requests to make this for an aftermarket power Antenna and the connectors are different, I could do that too, using the "different" connectors, provided those connectors are readily available.

I actually worked on the schematic for this yesterday. I am refining it to limit the number of wires that have to be ran from the switch back to the antenna. I want it to be a "Plug-N-Play" setup. I think the only extra wires that will have to be ran are a +12V power from the fusebox and the Remote Power from the radio. I'll know more once I do mine.

Re: Power Antenna & Stock Spoiler Clearance Issue

I think the light blue wire on my sony controls the antenna. It goes down once you switch to c.d. or even when you turn it off.

Yeah, my Pioneer's have a blue wire coming off the radio for the "Remote Power" for power antennas and for Amplifier activation, but they are a medium blue. One of the radios I had in the past had 2 remote wires, one was labeled power antenna and the other remote power. I don't know if they were electronically different circuits or if they were soldered to the same run inside the radio.

I think the "Blue wire" is industry standard.
