PNI-ML70

The PNI ML70 is a highly popular, compact magnetic mount mobile CB (Citizen Band) radio antenna designed for vehicles like cars, trucks, and vans. It operates in the 26–30 MHz frequency range (covering the 11-meter band) and is widely recognized for its robust build, low SWR values, and ease of installation. Core Technical Specifications The antenna is built primarily for drivers seeking reliable close-to-mid-range traffic communication. According to technical sheets, its key specifications include: Physical Length: 70 cm (including the base). Power Handling: Maximum applied power of 200 Watts. SWR (Standing Wave Ratio): Less than 1.2:1 at the center of the band when properly calibrated. Impedance: 50 Ohms. Material: Durable, weather-resistant stainless steel whip. Connection Thread: 16 mm thread, making it universally compatible with any standard PL-259 magnetic or fixed base. Performance & Range Communication Range: Under ideal open-field conditions with a standard 4W radio station, it can achieve a range of 8 to 10 kilometers. Real-world range will vary depending on physical obstacles like buildings, hills, or dense foliage. Tuning: The antenna can be finely calibrated by loosening an Allen screw on the base to slide the stainless steel whip in or out, preventing damage to your radio equipment and maximizing signal output.
