    UHF Military Satcom QFH Antenna description

    The UC-3004-531R, +4 dBic UHF Military Satcom QFH Antenna is a Quadrifilar Helix Antenna (QFHA), measuring 10 cm/4" OD x 46 cm/18" H, designed to operate through UHF Military satellites (MilSat). Coverage is Omnidirectional, when mounted upright. The Axial Ratio of a QFHA is stable over a broader range of elevation angles when compared to an X-Wing/Turnstile or Egg-Beater radiating structures. This MILSATCOM QFH Antenna is thus well suited for temporary and fixed sites, as well as mobile platforms over a wide spread of world latitudes. It also does not require a ground plane or a reflector for normal operation.
