Theres no better way to show you're part of the growing Helix community than to ditch that dorky radio-controlled-car-look antenna and plug in our Helix Stubby Antenna! This anodozed aluminum antenna is only 4" tall, and maintains excellent radio reception. Installation is less than one minute: it simply screws right in. No permanent modifications or drilling is required and this modification is 100% reversible. The Helix Stubby may not work on cars with Nav. If you're not sure, give us a call.
