Nautel Vector Series T h e C h a llenges Antennas used for navigational aids are usually small and inefficient, for both practical and economic reasons. This results in the following undesirable antenna characteristics: ATU-LP Antenna Tuning Unit ATU-500SR Antenna Tuning Unit ATU loading coil resistance can cause significant system losses. ATU-HP Antenna Tuning Unit Low antenna system efficiencies are common. High ratio of reactance to resistance creates a narrow band filter effect which can attenuate the sidebands of the radiated signal. Automatic tuning of the loading coil is necessary to...
