The most complete line of antennas from base, with superior mechanical characteristics, like D.J.S. Direct Joint System. Under this brand are reported the antennas with a direct joint system that gives, besides the external protection, a solid structure as for systems consist of a single element. The watertightness of the joints of the items is ensured by sealing rings. The external protection prevents oxidation of indoor radiant elements. The wind speed at which these antennas may be subjected meets professional, 40 m/sec for the X-X-X-7000/510/400/H-700H, 50 m/sec the X-300/X-200/V-2000/X-6000 and 60 m/sec the X-X-X-5000/50/30.
While with the D.C. symbol are electrically short antennas in massa for DC. The radiant element, the one placed inside the antenna, is put directly to ground in order to protect your equipment from surges and electrostatic discharges during lightning storms.
All antennas have an impedance of 50?, VSWR better than 1.5, can be attached to a pole with a diameter between 30 and 62 mm.
