The cross bars on my SUV are pretty aerodynamic. They look like a symmetrical wing shape. And, since I use my roof racks to haul long stuff around, I'm going to have to live with the drag.

----edit-----
I did lower the antenna drag by 50%. I lowered it half way down.

You shouldn't use silicone anything on a steel-bodied car. As the silicone cures and ages it releases acidic compounds that will initiate corrosion on any unpainted steel it contacts. The silicone windshield sealants are real bad about this and causing rust in the windshield channel. OEMs and glass shops use a gooey urethane sealant to install glass.

I'd go with the vinyl decal with some high quality 3M pressure sensitive adhesive backing or possibly a plastic plug like from Welcome To Caplugs

Hi All,

There is a non-corrosive silicone sealer. We use it for antenna work all the time. Its blue, and a little more expensive, and readily available. I have opened up silver plated connectors under this stuff 10 years after I sealed them, and found the coupling nuts still bright silver.

Standard RTV (Room Temperature Vulcanization) silicone is corrosive because the anti-polymerization agent is acetic acid (think orange juice,without the orange). As the RTV cures, the acedic acid is evaporating out of the blob.

This stuff is in a silver blue tube, usually, and in the gasket sealer area of most automotive, or hardware stores. It has a carboxyl smell to it. Here is a linke:
