I was looking at my 1985 300zx turbo the other day and I decided that I want to make it antennaless, as some of the newer cars(2006 toyota camry,honda prelude) What is the best way to do that, I can cover up that big hole but i just need to know how to make the antenna work like the other cars mentioned, thanks,

You could just go XM and then you'd just need one of those little antenna pods.

 

Get a standard type antenna (skinny tall ones) and lay it across the tail light area and zip tie or bracket it down. Or anywhere you want to hide it. But definetly ditch the power antenna for this.
I've heard it works very well by the tail lights though.

 

You can get hidden FM only antennas on ebay for about 20$. They work pretty well, but have to be mounted on glass to get decent reception. And good luck prying it back up after installed.

 

BMW's have plastic shielded antennas threaded up into the windshield "A pillar." That makes for a short wire distance too.
