300XP12 ASSEMBLY MANUAL
TOOL REQUIRED FOR ASSEMBLY: screwdriver, 11/32 nut driver or wrench, 7/16" and 1/2" socket or end
wrenches, measuring tape.
1. Assemble the boom using 8-32 X 1-1/4 screws and locknuts to join sections. (SEE DIMENSION SHEET).
2. Install Horizontal & Vertical Driven Element Assembly on to boom using 1/4-20 X 3" Bolt and lock nuts.
(SEE DIMENSION SHEET).

ASSEMBLING THE HORIZONTAL ELEMENTS

3. Layout the Horizontal elements by length and position as shown on the DIMENSION SHEET. Start with the
reflector (longest) element, install using a Screw, 6-32 X 1",SS.

ASSEMBLING THE VERTICAL ELEMENTS

4. Layout the Vertical elements by length and position as shown on the DIMENSION SHEET. Start with the
reflector (longest) element, install using a Screw, 6-32 X 1",SS. Note: The vertical element set is shifted
forward on the boom by 1/4 wave lengths. This increases isolation between element planes, improving
circularity and ease of phasing / matching the two element sets.
5. Install the boom to mast plate to the rear of the boom (SEE BOOM TO MAST DETAIL PAGE). Use two 1" U-
bolts and the stainless nuts and lock washers provided. DO NOT OVER TIGHTEN. 2" U-bolts (and stainless
steel nuts / lock washers) are provided for mounting the antenna to your NON-CONDUCTIVE mast or
crossboom. Other size u-bolts and cradles are available upon request.
