The performance of the product is closely related to the technical characteristics of the antenna under ideal conditions of installation and use: SWR lee then 1.2: 1, maximum applied power 250 W, impedance 50 Ohms, stainless steel etc. The communication distance of up to 10 km is reached in ideal working conditions: calibrated antenna, open field without obstacles, station with maximum legal power of 4W and standard reception. Any obstacle such as hills, mountains, buildings, walls can reduce this distance. The antenna has a 145 mm powerful magnet that provides the antenna with stability even at high speeds.
