PNIML145

The PNI ML145 is a highly popular, mid-sized Citizen Band (CB) mobile radio antenna designed for vehicles like cars, trucks, and vans. It features a length of 145 cm (57 in), which provides an optimal balance between highway clearance and a strong communication range of up to 15 kilometers under ideal, open-field conditions. The antenna uses a standard PL259 connector and a 16 mm thread, making it universally compatible with common PL-type magnetic bases or fixed vehicle mounts. Depending on the specific production batch or variant, it is available in two main configurations: the standard PNI house model or a premium edition manufactured in Italy by the renowned brand Sirio Antenne.
