The most complete line of base antennas, with technical characteristics and superior mechanics, such as DJS Direct Joint System. With this brand I am signal the antennas with a direct junction system which provides, in addition to external protection, a solid structure as for systems composed of a single element. The water impermeability of the joints of the elements is guaranteed by ring seals. External protection prevents oxidation of the internal radiating elements. The wind speed at which these antennas can be subjected to professional specifications, 40m/sec for the 7000/X-510/X-400/H-700H, 50 m/sec for the X-300/X-200/V-2000/X-6000 and 60 m/sec for the X-5000/X-50/X- 30.

While the DC symbol indicates antennas short-circuited to ground for direct current. The radiating element, the one placed inside the antenna, it is directly earthed in order to protect the equipment from surges and electrostatic discharges during thunderstorms.

All the antennas have an impedance of 50 ohms, with VSWR better than 1.5, they can be fixed to a pole with a diameter between 30 and 62 mm.
