If you are looking for an inexpensive antenna, this is it. It is a Taiwanese copy of the original German Hirschmann brand part, and fits the opening and successfully attracts radio waves. However, don't expect it to last long. They are very light weight and the mast breaks easily.
We HIGHLY recommend you purchase the original heavy duty stainless German antenna instead. It will last many years, and is relatively inexpensive. Click here.
