My 2011 NC antenna has deteriorated at the base where the plastic is dried out and broke, likely from the heat and humidity where I live in HI. I have it "repaired" i.e. held together short term via duct tape covered with black electrical tape. However, I need to replace it. I was wondering if anyone had experience with any short aftermarket antennas as to both fit and performance? I figure I need to order it online and a proven model will reduce both costs of returns if wrong and time. Thanks for any feedback.
