I must refer to the manufacturer's site for the exact product information.
Personal experiences:
Appearance:
As always, a matter of taste. Black, small and fits optically very well with the GPS module.
Haptics / processing:
The antenna makes a stable application. Meanwhile, I have the third antenna. This one I just had to replace after a raccoon or cat has bitten it.
The main reason for the purchase was for me that I have not always unscrew the antenna when I drive into the car wash. Since about 80% of the antenna are flexible, there are no problems here.
Reception:
Again, I can not see any disadvantages compared with the original antenna. In Greater Nuremberg this does not matter, but also at cross-country trips there are no problems.
Conclusion:
The antenna is not only convincing in price but also in the quality of the processing and reception.
