Antenna Mast Replacement

DVPTeg26 · Dec 9, 2003

Replacement of the power antenna mast on all G3 Integras. (94-01, 3DR or 4DR with POWER antennas) This was performed on Furious94LS' 4-Door GSR, but will apply to all G3 Integras.

- Tools Required:
- 10mm Wrench
- Philips Head Screwdriver
- Pliers
- Antenna Mast From Honda/Acura (39152-SM4-A03)

The problem... car off, antenna up.

Start by removing the clips that hold on the interior lining and bending/moving the interior trim out of the way to exopse the antenna motor assembly. (on 3DR models it is required that you remove the entire left side interior to obtain easier access to the motor assembly. refer to the rear seat removal article. This project can be done without removing the rear seats but its much easier when everything is out of the way).

Remove the antenna cap nut and black base from the car using the pliers in a counter-clockwise direction.

Loosen up the 10mm nut that holds the antenna assy to the bracket. Then slide the antenna down and maneuver it out of the bracket into the trunk area. At this time disconnect the power supply connector, breather tube and antenna reception feed wire.

With the entire unit out of the car, put it on the ground with the metal plate with the two screws facing up.

Remove the two screws to expose the antenna mast reel channel.

Simply lift, or pry depending on the situation, the plastic channel from the motor assembly and remove the snapped/ damaged/ broken reel.

Now go back to the mast and firmly pull it out of the reception tube. (note: If after a few tugs the mast is not comming out you will need a new reception tube as well. Chances are that it is so corroded that the tube has fused itself to the metal of the mast itself! Its not a bad idea to pick up the replacement mast along with the tube at the same time.)

After everything is out of the motor and the old mast has been removed from the system put the reel channel back into the motor assembly, put the metal backing plate back on and secure those two screws back onto the plate.

Now put the complete assembly back into the car. Attach the drain tube, antenna feed, and power connector. Make sure everything is secure now but DONT tighten down that 10mm nut just yet!

*This next step is where it helps to have another person around to help you out.*

Have someone go inside you car and turn ON the radio.

Now take the mast and put it into the tube.

Have the other person shut off the radio. This may take a few tries but eventually it will snake itself back down the tube the way it should be.

Next (with the radio off) re-apply the black base to the antenna hole and put the metal screw down cap back on top.

Now with one hand lift the motor from the inside and witht he other hand hand-tighten the metal cap.

Re-secure the 10mm nut so that its nice and firm. and with the pliers tighten down the metal cap (Do Not Overtighten! 1/4 turn after it sits).

Put the interior panels back together the way they belong and re-secure the clips.

Check for smooth operation and you're done!

Very helpful..Here are some additional tips that worked for me on '97 integra LS.

I too could not pull the mast out no matter how much force I used. My new mast assembly came with a thin metal sleeve around the black sleeve. It was this metal sleeve on the old antenna I could not get out of the threaded brass (?) reception tube. It did not seem corroded. Looks like there are internal tabs holding it in. Could not figure out how to get off the reception tube or find one online. Therefore, I cut the old antenna off down low & pulled out the old black sleeve. Then a 7/16 bit (?11mm in Japan) worked perfectly to drill out the remaining metal sleeve. Drill only as far down as the sleeve length on your new antenna. Be sure and dump out the debris. I had to file the top of the brass tube to remove the top thread I had damaged in frustration.

One person can thread the belt in. Thread it in as far it will go (teeth facing rear of car for me), turn the radio off, and move fast to guide the belt and sleeves into the brass tube.

Finally, took a little playing to adjust the antenna to go all the way down. Pushing down on the antenna a bit as it was cycling up and down (making a 1 second ratchet sound as the belt slips past the gear) did the trick and did not seem to do any harm.

Hope this helps someone

Did you do this after you removed the whole antenna assembly from the car? I pulled off the top nut and black cover piece then tugged the antenna over and over without success. If you could clarify what you wrote that would be great. I got as far as seeing the thread the cap screws onto and couldn't pull out the mast. I basically want to avoid removing the side panels and the entire antenna assembly.

My FREE solution:

Just used a small needle nose pliers to loosen the antenna nut counterclockwise, then finger turned counterclockwise to remove. I pulled out the antenna and cut the ****ty, truncated wire from the bottom of the antenna near the base of the mast, and placed it back in the tube after having turned off the radio with only the big telescope elevated. It's like a silver s2000 antenna now without spending any money or time doing a conversion. This is a free solve. I also disconnected the power clip so the antenna motor no longer activates when I turn on the radio. If you push the antenna all the way down, you won't get any reception on the radio. Leaving it up like this allows clear radio reception, and the best part is it's free, and still looks pretty cool. It's just a fixed short antenna now about the length of an s2000 antenna, but like I said, without having to do a conversion and waste time and money, and I think that's better than leaving it up and long. There are some masts on ebay that go for around 12-13 bucks, but I think I may just keep it like this. Kinda no point in fixing it if it's a common issue, and having it short like this makes no real difference in the reception so I'll probably keep it this way for good. Plus, it's kind of annoying to have that antenna go up and down when you turn on and off the radio b/c the motor makes noise for like 3 seconds both ways. It's nice that it's fixed without having to worry about that.
