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 and so forth.
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.
This antenna may also be tilted the use of the butterfly screw with a view to enter passages, garages or parking a whole lot of low height. Along with these situations, a tilt of more than 30 degrees isn’t advisable as it’s going to have an effect on the performance of the antenna.
