got a pic? as far as I know the antenna has never been mounted on the hood. maybe a previous owner did it.
Lol. That sucks man. Made me laugh outloud. Totally something I'd do.That surface is called the cowl. And it isn't a factory antenna. Definitely an after market product. All YJ antenna's in stock form, were mounted down on the side of the body.
If that antenna has a spring on the bottom of it, be careful of catching it on the wrong branch in the woods, when it releases it will most likely take out the windshield. I had a CB antenna on my CJ mounted in almost the same location, thought I was being smart by putting a spring on the bottom so it would flex instead of snapping the antenna. Yep, smart...smashed the windshield when it caught on a branch as I was backing up.
