Diamond V 2000 430 MHz 50 MHz vertical Antenna-144Mhz
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.
Warning-Counterfeit Diamond Products!
Unfortunately we found that fake diamond antennas were offered on the German and European market. Affected are the popular Omni-directional antennas for fixed installation of the "X-Series", but also some mobile antennas and equipment.
Even the packaging is deceptively copied from original-yellow sleeve diamond logo! But there are some subtle differences how to locate him fakes.
Bottom Part of Antenna
|Different shape. False is lucid, the original has a matte finish. Different stickers.|
Antenna and radio tube
Original tube with diamond sticker, original stainless steel radial thread and counter nut.
Forgery with brass clamp pressed on.
U-bolt and clamps
U mounting bracket clamps (X-510, X-700 and X7000 use different pliers)
- Counterfeit products are packed with bubble film, the antennae are not original.
- Press the button that closed the yellow plastic packaging is originally made of metal, using plastic fakes.
- Yellow packaging is folded down, giving it more stability. Fake products don't have this yellow box overlay.
- Instructions are printed on both sides with the original, and are simple cpoies fakes a one-sided picture.
Depending on the type of antenna points out one or more of these differences may occur. Please check carefully before suspecting a supplier without reason.
