Aircraft shorted loop antenna with impedance matching and amplification at feed point

摘要: An active antenna system for an airborne high frequency single sideband receiver comprised of a shorted loop type having inductive characteristic over the range 2.0 to 10.0 MHz and which is tuned resonance at selected operating by shunting its feedpoint selectively switched sets voltage variable capacitors. Also coupled field effect transistor adapted provide radio amplification. Impedance matching between output input further provided configured as emitter follower.
