® assuredcommunications™ RF-9070 VHF/UHF BICONICAL HIGH-POWER ANTENNA a VHF/UHF passive, high-power, broadband, biconicaldipole antenna The RF-9070 is a militarized, vertically- polarized, omnidirectional transportable antenna designed for groundto-air communication between 100 and 400 MHz. It is particularly useful for frequency-hopping systems due to its instantaneous broadband response and low VSWR. The RF-9070 also operates in the frequency bands used by a large number of commercial services, such as air traffic control, fire, police, utilities, and emergency services. The RF-9070 is supplied as a kit that includes the center hub assembly, 24 elements with threaded ends, 24 lock nuts, and a 10 foot coaxial cable. For corrosion resistance and durability the center hub and elements are made from lightweight aluminum alloy with E512 finish per MIL-F-14072. The center hub is constructed with two machined aluminum hubs that surround a center insulator machined from Delron 570. Within the hub assembly is a passive LC network that provides exceptional VSWR performance across the band. Electrical connection is provided by a type N female connector on the center hub. The coaxial cable allows connection to a radio up to 10 feet away. The RF-9070 antenna’s center hub provides a threaded 1.3-inch (3.3-cm) diameter hole for a mast. The optional RF-9071 is a mast pipe specifically designed to mount the RF-9070 antenna.
