This antenna will fit the '05-'06 Cobalts. It is 14" long and gets 100% reception. They go for about $21.41 shipped.($10.46 + $10.95 Shipping)

Great mod if you want a shorty antenna but don't want to lose your reception.

ooo nice find man. i kinda like that.

 

what about the 07's?

 

I like it but Ill probably just spend the extra 15 for the ARK

 

'07 will have to be drilled and tapped out another, 1mm I believe

 

Tricky, they are 6mm?

The guys on the Solstice Forums said they were 5mm. I just got mine in the mail yesterday but I am a late 06 with the 7mm stud. I was actually kinda hoping that you had the drill bit and tap so I could take it off your hands. Homedepot doesn't carry metric sizes. How's the reception?

 

I'm guessing since it fit fine that it's 6mm. I didn't measure though.

The reception is great, I get stations in better, ones that would previously fade out.

Though I really don't listen to FM Radio too much anymore since I have XM

 

nice... I thought i was gonna be mad close in drilling it out... looks like ill have plenty of room now. Thanks

 

up to 06 were 6mm, late 06 and up were 7mm

 

Looks good, but Im about to order a ARK one.
