It is highly recommended that the element be cut long and trimmed
down to the exact frequency desired.
5. Cutting the element may be easier by using the edge of a file or
grinding wheel to score the rod around its circumference. Then
snap it off with a pair of pliers. Always cut from the bottom of the
element.
6. Insert the element all of the way into the base assembly and
tighten with a 3/32" hexagon screw key.
