Short antenna for NA and NB is interchangeable and it’s shorter than the genuine Mazda antenna. The length of the antenna is 10cm. However, receiving sensitivity of radio frequency is on par with the original antenna.
The very short antenna is designed with a high sensitive coil rod that is wound up in a spiral (helical).
It’s easy to install and maintain.
Note: NB models will require the use of an NA antenna base or similar from another make/model to allow this unit to 'screw' in place.
