[Elecraft] Inverted L for 160 meters

[WA8JXM - Ken]

FWIW, I use WSPR to compare antennas.  That usually gives me a 
comparison list of more than a dozen receive stations.  I do multiple 
transmissions and then compare the differences.   There may be 
propagation changes during the different transmission periods but a 
couple of repeats seems to average that out.   It not only provides data 
in different directions but also different distances.

To get a same time comparison, I have used dual transmitters on slightly 
different frequencies but that gets complicated.
