Comments welcome.

Great job as usual, Owen. I would add a couple of
items.

1. Some commercial antennas, sold as G5RV's, deviate
from your information because they deviate from your
specifications and tuning procedures. They may need
to be tuned to your specifications.

2. The following statement is somewhat confusing.

Fig 1 shows the efficiency of a optimised typical G5RV.
Note that only three of these peaks coincide with an amateur
band, but 40m efficiency is 65% although not at the peak.

The resolution of the graph makes it difficult to know which
three peaks are in which three bands. Like 40m, you might also
state that 15m efficiency is xx% although not at the peak.
