If you are trying to build an end feed half wave (EFHW) antenna, the length is
in the name. A half wave at 40m is ~66 feet. Start with 67 feet and fold back
the end until you get a good SWR. You need a 49:1 transformer on one end to
get the impedance down to 50 ohm and to connect your coax. Mine is resonant at
10 through 40m.
