S2000 Antenna switch - with out cutting your old one, Full write up, lots of pics:) Options

[Legit94GT]

I have long since hated the giant fishing pole sticking out of the back of my car, rather than adding a switch or removing the antenna i decide to switch it out for a Honda S2000 antenna. Now the S2000 antenna screws directly into the 7th gen mount, and the 7th gen mount screws directly into the 6th gen parts. The antenna base you will come with a mounting bracket, but it isn't really needed as the whole things barely weighs anything.

You will need:
Honda S2000 antenna Part Number 39151-s2h-e01
7th gen Celica non powered antenna base Part Number 86309-20300


10mm socket
Philps screw driver
small needle nose pliers
Super Glue

1 piece of 3/4" inside diameter rubber hose ~ 6 inches long

1 piece nylon fitting 3/4" base to a 1/4"barb fitting



So start by buying everything first. I had no luck finding the 7th gen celica part in any junk yards or anything, So I had to order it through the dealer, as I did with the S2000 antenna. The powered antenna has a rubber drain hose coming out the bottom of it going out your trunk to drip on the ground, i did not know this and had to make a special trip to the hareware store to figure out that.

Once everything is bought, start by taking out the plastic peices on the inside of your trunk, hatchs and coupes are different, but for a coupe, you have to pull out the plastic trim piece on the top of your trunk then you can start unscrewing it everything. I only removed the section right underneath the antenna. With that stuff out of the way you can see the power antenna

There is one brass nut holding the whole thing to your car, use the 10mm socket and remove it. Now go back outside your car and use the small needle nose pliers to remove the chrome ring holding your antenna in place. You have to stick the tips of the pliers into the grooves to get it unscrewed. **be careful take your time with this, you can slip off and scratch your paint if you get in a hurry** Once it is all the way unscrewed remove the chrome part and the plastic peice.

With it off of your car it is easier to undo the two white wire clips. Once those are off you then have to remove the antenna wire, just pull it off. Now that it is all disconected put the brass nut back on and set it aside for resale:)

Now the plastic peice is meant to slide into the antenna base, but since we are crossing power/non power/7th gen/6th gen, the black plastic piece will not fit properly. You have to cut a little notch out of it
With the notch cut you can see that the plastic peice and chrome peice will now fit all they way down in the antenna mount. I removed the mounting bracket from the bottom of the antenna mount, it is not needed. The new antenna mount is made off a 3/4" pipe, in order to insure that no leaks get in your car you must plum this out of your car.

To do that you must take the 3/4" peice of rubber tubbing you bought and slide it over the antenna mount a few inches. Then take the nylon fitting and start threading it into the tube. It will be a tight fit, but that is good, the nylon will actually form the rubber into the threads. Once you have it started you will want to add some super glue to the nylon fitting and then start screwing it in more, this will create a water proof bearier. Once the glue is set you will want to take the rubber tubbing that came off of your old antenna and put it over the bottom of the nylon fitting.

Now once you install your antenna you wont ever have to worry about water dripping in:)

With your antenna finished go ahead and start putting it back together.

Once you have it in place and losely screwed together you will want to stop and make sure that all the rubber hoses are still where they need to be. Finish screwing the chrome antenna piece into the new antenna mount untill it is really really tight, and that is the only thing keeping it in place. Once you are happy with the fittament you can now plug in the antenna wire and screw on your new antenna:)


I hope that helps save you guys some time, i got screwed when it came to the water draining tube thing and that took me forever to figure out and go shopping for:( With everything listed and clearly explained i would say that it should take no longer than 25 minutes to do this. It cost me $30 for the antenna and $50 for the mount, and like $3 for the rubber tube and nylon fitting. I had to order everything through the dealers as we dont have ANY 7th gen celicas in our junk yards up here:( but grabbing on out of a wrecked on would be just fine. So for less than $100 and 30 minutes of your time you have a new updated look for you car;)

Great write up

Although i did things slightly differently as i found mine leaked :s

I swapped the top rubber cupping thing on the aerial bases around, which meant when I screwed the retaining nut in, it made it better watertight. Also, no need to cut the plastic base from the 6th gen.



^ 7th gen aerial with its original top piece



The one on the left this the 7th gen base with 6th gen top piece on it - this created the better seal

The mounting bracket that you removed i kept. I did this because the aerial wasn't supported enough, and i found that when i moved it slighty i could see my panel flexing :s All i did was take the bracket, bend it, and put a new bolt hole in it and it worked perfectly.



Now it doesnt leak water Plus its reinforced
