21,050kHz (CW subband), remove the tape and INCREASE the length of the
antenna. This adjustment is critical, so you will have to increase only about 5mm
(1/4”) on each side, reassemble the antenna and give the SWR. If you want the
SWR to be lower at a higher frequency, SHORTEN the antenna’s length.
Note
that this operation requires a lot of patience until you get the desired result.
• Having obtained the ideal resonant frequency, fasten the tip of each element
using the cable gland.
