AIS -Black box engine – Low cost single channel receive with automatic switching between channels with supports for cjart main class A transponder messages. Spain North and South inc Balearics aantenna Canarias. Admiralty Total Tides world coverage. The yellow marker shows minimum SWR at 5. Malacca Straights and Singapore. Recall this is SWR normalized to 50 ohms. Upgrade lite to v6.

Smith chart of sweep of antenna 1.

Reactance first goes negative, then loops back positive. But, the antenna is not constant impedance, so we’re seeing the varying antenna impedance transformed by the varying electrical length transmission line. Over that range, the minimum SWR is at The yellow marker again vr6 the mimimum SWR at 4.
