the RF-9070 is a militarized, vertically- polarized, omnidirectional transportable antenna designed for ground- to-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 thr eaded ends, 24 lock nuts, and a 10 foot coaxial cable. for corrosion resistance and durability the center hub and elements ar e made fr om lightweight aluminum alloy with e512 finish per mil-f-14072. the center hub is constructed with two machined aluminum hubs thatsurr ound a center insulator machined fr om delr on 570. w ithin 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 antennas center hub provides a threaded 1.3-inch (3.3-cm) diameter hole for a mast. the optionalrf-9071 is a mast pipe specifically designed to mount the RF-9070 antenna. assured communications ?
