DIAMOND - BC103 - BASE VHF FIBERGLASS ANTENNA - WIDE BAND CONTINUOUSLY FROM 144 TO 174 MHz
Now a complete line of omnidirectional base antennas is available for VHF or UHF tunable in band.
Supplied with the antennas there is a graph for cutting the radiant element for the resonance on the desired frequency.
The external protection prevents the oxidation of the internal radiating elements, the wind speed to which these antennas can be subjected respects the professional specifications.
All antennas are D.C., that is short-circuited to ground for direct current: the radiant element, the one placed inside the antenna, is directly grounded in order to protect the equipment from overcurrents and electrostatic discharges during thunderstorms.
All antennas have the SO-239 (MJ) connector, with an impedance of 50Ω, with R.O.S. better than 1.5 on the resonant frequency and can be fixed to a pole with a diameter between 30 and 62 mm.
