Description
The AX-71C antenna is a compact VHF/UHF omni-directional receiving and transmitting antenna for professional and consumer surveillance and monitoring applications.
The antenna covers the frequency range of 25 to 1500 MHz, offering a typical VSWR figure of less than 1.5:1.
While designed to be entirely general-purpose, the AX-71C Wideband Discone Antenna is especially suitable for the WiNRADiO range of VHF/UHF receivers.
The principal elements of the antenna are constructed of austenitic stainless steel, 303 grade. Austenitic (chromium and nickel content) stainless steels have high ductility (i.e. ability of a metal to plastically deform without breaking or fracturing), low yield stress and high ultimate tensile strength, when compared to a typical carbon steel. They also feature very good corrosion resistance.
The choice of materials and the durable construction of the AX-71C antenna will ensure trouble-free operation for many years. The antenna was designed for rapid assembly, with easy-to-follow assembly procedure supplied with the antenna.
