Dipole pair DS2 VHF was designed according to special technical specifications, including strict requirements on operating frequency bandwidth, circular pattern, low VSWR, high power conduction, maximum lightning protection and corrosion stability. This construction is the main component for high VSWR antenna array building.
DS4 VHF and DS8 VHF antennas represent array antenna with heightened gain assembled using two or four DS2 VHF antenna pairs connected by adders. These antennas are very easy to transport due to their collapsible construction, in spite of large overall dimension in assembly.
