HF Short 40 Meter Mobile HF Stick Antenna 4ft

I ordered the 40m HF Stick and what I received, well I don't know. The box has a sticker on it telling me it's a cb antenna, the antenna has a sticker on it, telling me it's 40m. The manual tells me to extend the stinger to 28" for 40m but the stinger is only 12" long. So I assume it's a 11m antenna. I am overseas in the military so sending it back would be quite a hazzle. Lesson learnd, I only buy from sellers I know.

Have used one for over a year now, wish they had the same thing for 75 meters.
