Good enough if you can't have or don't want a regular antenna
This product is so much better than the Zhol antenna. Better build quality, more appropriate length for FM radio and a better coaxial cable. But still it was disappointing when compared to the short 14" antenna that was stock on my car. Much better than Zhol but noticeably worse than the stock antenna. But if you need an internal antenna this is probably the best choice. It is worth twice the cost of the Zhol so in this sense it is a good value because it outperforms the Zhol.
