Has anybody plotted the radiation patterns for inverted Ls on 160? I'm
particularly interested in those for relatively-low antennas, say 40 ft
max, over fairly-poor ground such as desert sand with the water table
perhaps 120 feet down.

Today I uploaded a short 6 minute video showing how to use the Kiwi radios
located all over the world to test your transmit antenna.
How is the front-to-back on your 4 square really performing?
It the dipole or the vertical performing better on the DX path?
Make an azimuth polar plot of your Yagi and see how it compares to modelling.
How does the pattern change across the band?
This is not a new thing, but in this video I describe the method for those that
may not be familiar with it.
No test equipment is needed. All that’s required is a PC sitting beside your
radio.
Using the “S-meter” function on the Kiwi radios makes it quick and easy to
record signal levels from your transmit antenna.
This method is far more accurate than trying to estimate a signal level while
watching a bouncing analog or digital S-meter.
