Learn something new every day. I can verify that the rear antenna does in fact adjust itself to the different FM radio frequencies. Played around with it last night and sure enough depending on the station is extended different heights. I find it hard to believe that it would do that and not be part of the FM reception. That's not to say you could put a solid mount on though.

hey guys - actually unplugged the power supply to it a few years back. While it wasn't too hard to do (less than an hour but some minor scrapes on my hand) I just took out a few screws and trim pieces here and there in the trunk to access it. I'm glad it is safely stored in the rear quarter panel. Figured it was easier than watching it get stuck in the up position; not to mention I never used it. Prefer my iPod to the radio.

If pulling the fuse does not work, you could disconnect the antenna mast power at the auto control relay located back by the mast itself.
Pulling the fuse did not remove power from the antenna. Can someone please upload the diagram for disconnecting the power from the antenna at the antenna mast (trunk)?

Take a look at this thread... https://www.clublexus.com/forums/sc-...roblems-2.html I believe there are comments that apply.

I finally unplugged the power to the antenna (no more noise when switching stations ). I replaced the extending antenna with an after market stubby antenna for aesthetics. Radio quality seems to be as good as it was previously. *UPDATE: After driving it for a while after the install, I can tell that radio signal is not as strong as it was before I installed the stubby* Here are the steps with pics to unplug antenna:

1. From VVTiBob, I took out existing antenna per these PDF Instructions.
2. Opened the trunk and took out the floor/wall lining. Just look for all the screws and plugs, it's fairly simply. You'll need a Star Key to get one of the screws off, auto stores carry these. You'll need to disconnect the trunk light (attached to lining) and disconnect drain tube (attached to lining)
3. Unplugged the power to the antenna (see pic)

Nice mod! I like it!! You even updated your signature! LOL Quick work too

You should paint your chrome bezel around the antenna black to match your paint or remove it. Kinda looks out of place with the rubber antenna now IMO.

You may need to apply a small amount of primer on it with a touch up brush...then I'd get your touch up paint at Toyo dealer (cheaper than Lexus) with your paint code to do it right.

My antenna just broke last week and I have received a replacement mast and was going to install it today (most of the mast cable is stuck in the motor) but now I am undecided if I want to go with a chrome stubby or the OEM mast since I have to remove the entire antenna to get the mast cable out. Thanks Redliner8!

You're welcome. I would go with the stubby or just unplug the OEM so it doesn't extend.

scdroptop, I painted the decorative nut black. I think it looks better:

It must be the cold weather. Mine broke Dec. 20th and it also broke off in the motor. I hated to remove so much of the trunk interior to get to it, but bit the bullet and installed it Sunday. Now here's where I get the DA award. After removing, fixing and reinstalling the motor, I forgot to plug in the antenna RCA plug. Had to take the trunk interior apart a second time. So don't be rushed like me...plug in both the power and the antenna plug.

Don't you just hate that when it happens. Forgetting to do a step and immediately realizing it after everything is tucked in?

Happened to me many times. Take your time. As the saying goes, measure twice, cut once.

This definitely reminds me of the antenna mod I did for my son's 1995 Camry. Raplaced the antenna with a Honda S2000 mast, complete with mods, looks professionally installed. When the Camry was totalled, I yanked the antenna out, like I have a place to put it. It just looks good.
