10. Use this barron's attention:

a: vibrator as close as possible to the Barron and try to straighten;

b: vibrator length is recommended more than one wavelength, the shortest try to ensure that half a wavelength (at this time the standing wave can be as high as 1.8 or so);.

c: grounded or not is not important.
