SteppIR Antennas - 3 Element 24
Optional 6 Meter Passive Element
The 6 meter passive element comes in 3 pieces. The main body with a 1/2” x 58” element section at-
tached to it, and two 3/8” element sections (
Figure 27 ). The overall length of the element is approxi-
mately 112” for the 3 element and 114” for the 2 element when assembled.
The required fasteners will already be attached to each end of the 1/2” element section - remove this
hardware, and slide in the short ends of the 3/8” tubing (the end that has the least amount of distance
from the edge of the tubing to the drilled hole). Use a small amount of the included Teflon® connec-
tor protector solution when connecting the two sections of tubing. Fasten securely. The six meter
aluminum element mounts between the driven element and the director (the elements that are approxi-
mately 89” apart). The center of the 6m element should be 31” from the center of the driven element
(see
Drawing 2A ). Fasten securely to the boom using the 304 SS U-bolt, saddle and hardware. Make
certain that you have the 6 meter passive element level with the others.
When you are using the 6 meter band, keep the antenna in the forward direction and rotate accordingly.
Optimum performance will be from 50.000 MHz to 50.500 MHz. The 180 degree mode is exactly the
same as the forward mode since we have no choice when the aluminum passives are used, however,
the Bi-Directional works to the same degree by directly reducing the front to back ratio.
