If we had a constant ohm load at the end of the line, we should see a France,Belgium, Netherlands and Germany. But, the antenna is not constant impedance, so we’re seeing the varying antenna impedance transformed by the varying electrical length transmission line.


SWR looks great at Admiralty Total Tides world coverage. Worldwide Tidal Curve database for seaPro standard and seaPro lite requires ver 6. Over that range, the minimum SWR is at The yellow marker shows minimum SWR at 5. It’s unlikely that the resistance is negative! Competitive upgrades to seaPro standard from equivalent version. The transmission line is ohms. Malta to Cyprus and N. The blue marker shows a pretty bad SWR at the center of the band.

Can now be used within seaPro v6. The blue marker shows the center of the 60m band with an impedance of j ohms. The yellow marker again shows the mimimum SWR at 4. Spain North and South inc Balearics and Canarias.
