For 20 meters (14.175 mHz center frequency) I got:
for frequency 14.175 mHz.
total length 32 feet 11 inches or 10.052 meters.
shorted length length 32 feet 9 inches or 8.469 meters.
difference length length 0 feet 7 inches or 0.792 meters.
stub length length 0 feet 5 inches or 1.052 meters.


Anyone have any ideas? Will this work? How do I calculate the stub
length?

Think you have some errant decimal points in the last three English/metric
conversions
