#2 - ELEMENT ASSEMBLY & MOUNTING
(For Vertical or Horizontal Polarization)
3
FIGURE C
The elements are made up of one pre-drilled and slotted 3/4" (1.9 cm) O.D. center tube and two pre-cut 5/8" (1.59 cm) O.D. end tubes. Assemble
the elements using Figure B for horizontal polarization or Figure B-2 for vertical polarization. Slide the tuning strap (69) on one of the EA tubes.
This will be the driven element #2. Place telescope clamps (409) loosely on the slotted ends of all EA tubes. Note that the EC tubes must be used
with the EA tube on which you placed the tuning strap (69). Attach caps (27) to the end of each element. Mount the elements to the boom (Figure
C). Refer to figure D for mounting the driven element with the connector bracket. Mount the connector with the threads (socket) pointing to the
mast mount. Adjust the antenna to your preferred portion of the 6 meter band using Table 1 if you've chosen horizontal polarization or Table 2 for
vertical polarization. Tighten all connections.
