Super Slim Cable for Easy Installation

For easier installation, the A139 Pro 1CH now comes with 2.8m ultra-thin coaxial cable and miniature connectors.

When compared to traditional rear cables, it is simpler to install and can be better hidden on the car roof! This reduces the electromagnetic interference to other in-car electronic devices such as car multimedia systems.
