For that price, I'll bet its a 3' SS whip. NGP Firestics are more like $50. I mounted my SS whip to a spring mount so it can bend with the branches. Once you get the new antenna, you'll have to hook up an Swr meter to the antenna cable as it enters the Cobra radio box. Assume your's is a Cobra all in one like mine, all controls on the mike. It takes a contortionist to squeeze in front of the driver's seat, using only one arm, to connect the Swr meter. Then several trips up the ladder to make small (1/16") adj to the length of the antenna until the SWr is below 1.5. Someone on another forum was promoting the use of CH 13, I believe, for use by RV'ers.
