DIAMOND X-700 HN 144/430 MHz 7.20 M.
TECHNICAL SPECIFICATIONS
The most complete line of base antennas, with superior technical and mechanical characteristics, such as D.J.S. Direct Joint System. This brand indicates antennas with a direct joint system that provides, in addition to external protection, a solid structure like systems composed of a single element. The water resistance of the element joints is guaranteed by O-ring gaskets. External protection prevents oxidation of the internal radiating elements. The wind speed these antennas can withstand complies with professional specifications: 40m/sec for X-7000/X-510/X-400/H-700H, 50 m/sec for X-300/X-200/V-2000/X-6000, and 60 m/sec for X-5000/X-50/X-30.
Meanwhile, the D.C. symbol indicates antennas short-circuited to ground for direct current. The radiating element, located inside the antenna, is directly grounded to protect equipment from overcurrents and electrostatic discharges during thunderstorms.
All antennas have a 50 ohm impedance, with VSWR better than 1.5, and can be fixed to a mast with a diameter between 30 and 62 mm.
