CB Antenna Noise (Wind)

[f5fstop]

Finally received my antennas for the final stage of the CB install; however, after the install and a drive around for a day, I have noticed the wind noise is very loud; with or without the springs. I?m using two 3? Firestik (Firefly) antennas with HD stainless springs. It?s a dual-phase system, one mounted at the rear of each roof rail. (SWR is around 1.2, and the setup appears to be a strong one, but the wind noise may drive me to drinking.)
Wondering if a thinner, smoother type (possibly a whip) antenna would create less wind noise? Anyone have any experience with this subject? (My Jeep had a 4? Firestick, mounted to the rear tire carrier, and I never experienced this type of wind noise.)

Communicating with Walcott, they suggest that a Hustler FG27S, which is 1/8" wide 48" tall stainless steel and extends out to little more than 1/4" in the middle where the load coil is located MAY solve the problem. They cannot say for sure. (I might purchase one antenna and drive around and listen.)

Anyone ever have a problem like this, and if so, did you fix it or just learn to live with the noise?
