This automatic antenna tuner is perfect for this new reality. It will tune a much wider range of impedance than the tuner built into your rig. It is small, lightweight and can provide years of service free antenna tuning for the 160-6m ham bands. Switch between two antennas. More memory!<br \/>\nIt features LDG&#8217;s state-of-the-art, processor-controlled Switched-L tuner. It will match virtually any kind of coax-fed antenna, including Yagi&#8217;s, dipoles, inverted Vs, slopers, loops, just about anything.<br \/>\nThe AT-200 features over 16,000 3D memories, automatically storing tuning data for frequencies and bands as you use them. It learns as you use it, adapting itself to your operating patterns for faster and faster tuning.<\/p>\n<p>Specifications:<br \/>\nFast tuning .1 seconds for memory tuning; .5 to 6 seconds for first time loads<br \/>\nMicroprocessor controlled<br \/>\nTwo position antenna switch.
