The 43 foot antennas are very short (low inductance, poor efficiency) on 160.
Only my very best tuners will tune them… and tuning doesn’t make them
efficient, it only makes them not destroy the radio with reflected currents.
The best solution is to top load a 43 food antenna and turn it into an inverted
L. Of course, if you have trees, a wire will do the same thing without needing
the 43 foot aluminum part.
