Diamond BC-100 - VHF 136/174 MHz vertical antenna

BC-100 Calibratable vertical antenna 136 / 174 MHz

The most complete line of base antennas, with superior technical and mechanical characteristics, such as the DJS Direct Joint System. This mark indicates antennas with a direct junction system which gives, in addition to external protection, a solid structure as for systems composed of a single element. The water impermeability of the element joints is guaranteed by ring gaskets. The external protection prevents oxidation of the internal radiating elements. The wind speed to which these antennas can be subjected respects professional specifications, 40m/sec for the X-7000/X-510/X-400/H-700H, 50 m/sec for the X-300/X-200 /V-2000/X-6000 and 60 m/sec 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, is directly earthed in order to protect the equipment from overcurrents and electrostatic discharges during storms.

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